November CPS Turtle Data

Yertle on November 1st

As we know, our Blanding’s turtles are getting larger by every week.  On the top of this post, is the data from all the turtles that are being headstarted by 4th grade students in Concord Public Schools.  Your job is to look at this table of data and answer the following questions: (by Friday)

1.  What is the range of the turtles’ weights?

2.  Are there any outliers in this data?  What are they?

3.  What’s the median turtle weight?

4.  Find other turtles that also had Mother ID 2033.  How do Yertle and Bowser compare to their siblings?

5.  Why do you think there is such a large range?

6.  What is your prediction for how much Yertle and Bowser will weigh next month based on their monthly weigh-ins to date?  What are you basing your prediction on?

Predict what Yertle and Bowser will weigh on Dec 1st

    The range is from 12g – 37g.
    I think12g,13g are the outlier.
    22 g is .the median turtle weight.
    Actually,most of there siblings are really weak compare to Yertle & Bowser ,only Quigley weighs 28g.
    I think there is such a large range because like most of them weigh about 20g – 30g.
    Next month they’ll probably weigh about 40g to 60g because they are actually doubling their weight they weighed each month.

    1. The range is 12 (g)-37 (g).2. The outliers are 24 (g) and 37 (g).3. The median is 22 1/2 (g).4. The turtles are Smallfry Teddybear Quigley both Yertle and Quigley weigh 28 (g) Bowser’s weight is doubled Teddybear’s weight Smallfry is 2 (g) away from weighing the same as Teddybear.5. I think ther is a large range because some school’s could be feeding the turtles more often so they weigh more.6. I predict that Bowser will weigh 44 (g) and I think Yertle will weigh 42 (g) because both of them gained 14 (g) in October so I think that Yertle and Bowser will gain 14 (g) again.

    1. The range of the turtles’ weights is from 12 grams to 37 grams.

    2. Bubbles is an outlier because he is 4 grams heavier than the rest of the heavy turtles.

    3. The median weight is 22 grams.

    4. Bowser is heavier than all its siblings at 30 grams, and Yertle and Quigley are the same weight at 28 grams. Then Teddybear is the second lightest turtle at 15 grams, and Small Fry is the lightest at 13 grams. I’d say that Yertle and Bowser are heavier than most of their siblings.

    5. I think there is such a large range because some turtles are probably eating more pellets. Also, some were born very light.

    6. I think Bowser will be 41.5 grams because the median in the range of 7 – 14 grams in monthly weight gain is 10.5 grams and 30 grams + 10.5 grams = 41.5 grams. I that that Yertle will weight 37 grams because the median in the range of 4 – 14 grams in monthly weight gain is 9 grams and 28 grams + 9 grams = 37 grams.

      I liked how you put spaces inbetween all the questions and numbered them so we could tell them apart. I also like how you spelled out ‘grams’ instead of just writing ‘g’. It’s a really good blog.

    The range is 12g-37g. I think there are outliers, and they are 32g, 12g, & 13g. The median turtle weight is 22 1/2. Teddybear, Small Fry, & Quigley are also turtles of Mother 2033. Teddybear weighs 15g, Small Fry weighs 13g, and Quigley weighs 28g. Yertle weighs 28g, and Bowser weighs 30g. Both Quigley and Yertle weigh 28g, but otherwise Teddybear and Small Fry have a little bit (more like a lot) to go to catch up with Yertle and Bowser. Maybe there is such a large range because some classes are feeding the turtles less pellets and some classes are feeding the turtles mroe pellets. Maybe the turtles simply don’t eat as much. Who knows? I think that Yertle will weigh 40g-45g and Bowser will weigh 43g-47g because they both are doubling their weight (roughly).

    1.) The range of the turtles at Thoreau, Alcott, and Willard is 12 grams-37 grams.
    2.) The one outlier in this data is 37.
    3.) The median for this data is 22.
    4.) The 3 other turtles that have the mother ID of 2033 are Teddy bear, Small Fry, and Quigley. Yertle and Bowser have similar weights to Quigley, but Teddy Bear and Small Fry have some of the lowest weights on the chart.
    5.) I think the range is so big because all of the turtles have a different environment. I think this because if you look on the chart most of the turtles in the same classroom have a similar weight.
    6.) I think both of the turtles will be in the low 40’s. I think they will both have the same weight because Yertle is catching up to Bowser with the number of pellets he eats and Bowser is eating less.

    1. I did a graph and the range was 12-37. The outlier was 37. The cluster was 17-24. the list of range is 12,13,15,15,17,18,19,20,21,22,23,23,24,28,28,28,29,30,33,37. The median was 22 and a half.
    2. Teddy bear had the same mother #2033 same as Bowser and Yerttle. The similar thing about Teddy bear, Yerttle and Bowser is that Bowser is bigger than Teddy bear and Yerttle. I also notice that Bowser’s weight is double from Teddy bears weight because 15 grams+15grams=30 grams.
    3. I think that the range is so big because the Blandings Turtles are eating different amounts of pellets.
    4. I think Bowser is going to weigh 44 grams and Yerttle is going to weigh 42 because they both gained 14 grams.

    1. The range of this data is from 12 grams to 37 grams.
    2.An outliar to this data is 37 grams. It is an outliar because the closest number is 33 grams.
    3.The median for the data is 22.5 grams.
    4.I think they are doing better than their siblings because their sibling weights are 15 grams and 28 grams and Bowser and Yertles weights are 28 grams and 30 grams. Bowser is doing better than all of the siblings and Yertle is tied with one and doing better than the other.
    5.I think there is such a large range because some turtles are eating a lot like 50 pellets a day at least and some are not eating a lot like 20 pellets a day.
    6.I think Yertle will be 38 grams because he gained 4.5 grams in one month and in another month he gained 14 grams. I think he will gain ten grams next month because that’s a little more than half of what he ate in the last two months. I think Bowser will gain 14 grams because one month he gained 6.7 grams and the next he gained 14 grams. I think Bowser will eat as much as last month.

      I forgot Small Fry who is 13 grams. Bowser and Yertle are both doing better than him so my answer stays the same.

    1. The range of the turtles weights is from 12 grams – 37grams.

    2. I think Trouble and Small Fry are the outliers.

    3. The median turtle weight is 22 grams.

    4. Teddybear, Quigley, and Small Fry are also brothers or sisters of Yertle & Bowser.Teddybear weighs 15 grams & Small Fry weighs 13 grams and they are actually really weak as compare to Yertle and Bowser.Only Quigley weighs as much as Yertle. So, the others need to catch up!

    5.I think there is such a large range because some turtles are not eating well so…

    6. Next month they’ll probably weigh about 40grams – 60 grams.Because they are actually doubling their each month.(roughly).

    1) The turtle’s weights range from 12 grams to 37 grams.

    2) I only see one outlier, and it is 37 grams. It is an outlier because it is 4 grams away from the surrounding data.

    3) The median turtle weight is 22.5 grams.

    4) The other turtles with mother 2033 include Small Fry, Quigly, and Teddybear. Quigly weighs 28 grams, the same as Yertle. Yertle and Bowser are heavy compared to their siblings. Bowser is twice the size of Teddybear, and Small Fry really lives up (or should I say down?) to it’s name. That little guy is only 13 grams!

    5) I think the turtle weights differ so much because some people might feed them more or less or maybe some turtles are more active and, as a result have to eat more to have that energy.

    6) I predict they will weigh roughly around 60 grams around December 1st. This is because they have been doubling their weights lately, so I bet they’ll do it again.After all, they’re still growing like grass.( Or maybe duckweed)

Yertle and Bowser are doing the best because they weigh about double the amount of Small fry and Teddybear. The third sibling Quigley weighs the same as Yertle (28 grams) and Yertle is lighter than Bowser (30 grams). 5. Maybe there is such a large range because some schools don’t feed the turtles as much. 6. I think Yertle will weigh 52 grams. I think Yertle will gain 24 grams which is 10 grams more than the previous month which was 10 grams more than the previous month. I think Bowser will weigh 60 grams. I think Bowser will gain 30 grams because each month his weigh gain doubles.

    1. The range of the data is12 grams – 37grams.
    2. The outlier is 37grams.
    3. The median is 22.5 grams.
    4. Quigley is one of Yertle and Bowser’s siblings Quigley is the same weight of Yertle. Out of all of the siblings Bowser weights more.
    5. I think the range is so spread out because different classes are feeding there turtles different amounts of turtle pellets.
    6. I predict that yertle will be 40 grams because he/she has been doubling her/his weight. I predict that Bowser will be 36.2 because I doubled his/her birth weight 4 times and I got 36.2.

    1. The range of turtle weights is 12 – 37 grams.
    2. The outlier was Bubbles who weighs 37 grams. Our turtles, Yertle and Bowser only weigh 28 grams and 30 grams.
    3. The median weight is 22 ½ grams.
    4. Teddybear had mother #2033 like Yertle and Bowser but only weighs 15 grams. Yertle weighs 28 grams and Bowser weighs 30 grams. That’s a lot more than Teddybear. Small Fry also had mother #2033 but Small Fry weighs even Less than Teddybear. Small Fry only weighs 13 grams. Quigley, like Yertle weighs 28 grams. Quigley also had mother #2033. I think our Turtles Yertle and Bowser weigh a lot compared to some of the other turtles that had the same mother as them. Quigley weighs a lot too.
    5. I think the range was so big because some turtles were a lot hungrier and ate more than other turtles.
    6. I think in one month Bowser will weigh about 44 grams because Bowser weighed 14 grams less last month. I think Yertle will weigh 44 grams next month because Yertle weighed 14 grams less last month.

    1.The range of the turtles is from 12 to 37 grams.

    2.I think the outlier is 37(Bubbles)

    3.The median is 22.5 grams.

    4.The other turtles of mother 2033 are Quigley(from Willard),Small Fry(from Alcott)and Teddy Bear(from Alcott).

    5.I think maybe because their birth weights are different and maybe some are eating more.

    6.I think by next month they will weight between 50 to 55 I based it on the monthly graph.

  15. 1. The range for the turtle’s weights are 12-37 grams.
    2. The outlier for the data is Bubbles. Bubbles weighs 4 more grams than the 2nd heaviest turtle.
    3. The median for the turtle weights is 22 grams.
    4.Bowser, Yertle, Quigley, Teddyear and Small fry are all siblings. Out of all the siblings Bowser is the heaviest. Yertle and Quigley weigh the same amount of grams with 28 grams. Then comes Teddybear with 15 grams . So Small fry is the lightest with 13 grams.
    5. I think that there is such a big range because some of the turtles were born small and light like Small fry and others were born big and heavy like Bowser.
    6. My prediction for Yertle and Bowser’s weights for the beginning of December, would be about 2 grams heavier.
    Yertle would be around 30.1 grams for my guess and Bowser would be around 32.3 grams for my guess.

    1.The range of the turtles weights are 12grams-37grams.

    2. There is one outlier which is 37grams.

    3.The median weight is 22.5grams.

    4. The turtles that have mother 2033 are: Teddybear from Alcott, Small Fry from Alcott, and Quigley from Willard. Some of the things that are different are: Small Fry and Teddy Bear do not weigh that much, in fact Small Fry is the second lightest unlike Bowser who is one of the heaviest turtles.

    5.I think there is a big range because some classes might be feeding their turtles more than other classes. Another reason is that some turtles might naturally eat more or if they eat less they might have a disease.

    6. I think that next month Yertle will weigh around 55 grams because in November he doubled his weight and 28grams plus 28grams plus 56grams and rounding that up to fives would equal 56grams. I think that Bowser next month will weigh 58 grams because last month his weight was two grams short for doubling his weight and if you add 30grams plus 28grams it equals 58grams. Also, last month Yertle weighed two grams less than Bowser did and if my predictions come true that will happen again with 58grams and 56grams.

      1) The range of the turtles from Willard, Thoreau, and Alcot is 12g- 37g.
      2) There are a few modes for this data and they are 15,23,and 28,
      3) The median for this data is 22.5g.
      4)Some of Yertle and Bowser’s siblings are Quigly from Willard, Teddybear from Alcot, and Smallfry from Alcot. Some things that I noticed about the differences in the weights of the family are that Teddybear and Smallfry are very light compared to Yertle, Bowser, and Quigly. I also noticed that Quigly and Yertle are the same exact weight.
      Bowser is just heavear than all of them!
      5) I think there is a big range but I wasn’t very surprised because that is a lot of turtles in all 3 schools. I am surprised that the lightest turtle was 12g because that is probobly pretty close to some ot the turtles birth weights. I thnk that the reason there is such a small turtle is that they are probably one of the turtles that won’t eat the turtle stuff and will onlt eat words.
      6) I think that next month Yertle will weigh 40g because in October weighed 14g and in Novemer he weighed 28lbs and that is a 14g differenc so I think that he will weigh almost the same differece
      as the last two months so I think that he will weigh 40lbs. Next month I think that Bowser will weigh 44g

    1. The range of the turtles’ weights is 37 grams -12 grams.
    2. I think there is only one outlier in the turtles’ weights which is 37 grams.
    3. The median of the turtles’ weights is 22.5 grams.
    4. Teddybear, the turtle with the same mother of Yertle and Bowser is 15 grams less than Bowser and 13 grams less than Yertle.
    5. I think that the range is so big because other classes turtles could be eating more food than Yertle and Bowser or they could be eating less or the other classes could be giving their turtles different food than the food we give Yertle and Bowser.
    6. I think Yertle and Bowser are almost doubling their weight that they had the month before.

    The range of the turtle data weight is 12 grams to 37 grams. 12 and 13 are the outliers. The median is 22 1/2 turtle grams. Bowser was the biggest, Small Fry was the smallest sibling. Maybe heat or how much they ate made a difference. I think Bowser and Yertle will gain 21 grams because they keep gaining factors of 7.

  19. 1. The turtles’ weights ranged from 12 grams to 37 grams.

    2. Bubbles is an outlier because it weighs 37 grams and other turtles are all at least a whole 4 grams lighter.

    3. The median of the data is 22 1/2 grams.

    4. All of the turtles that are related to Yertle and Bowser weigh under 20 grams, except for Quigley who weighs the same as Yertle at 28 grams.

    5. I think there is such a big range because maybe some don’t like the pellets so they don’t eat as much, while others love them and absolutely devour the pellets, like Bowser.

    6. I think they both will be around 60 grams maybe a little more maybe a little less.

    1)The range for the turtles is 12 to 37 grams. I thought this was a huge range because most turtles weigh about 9.5 grams at birth meaning that Pancake only gained 2.5 grams in 3 months !

    2)There was one outlier which was Bubbles who weighed 37 grams. Which was the heavest weight in the district!

    3)The median weight was 22 grams.

    4)I think that Quigly and Yertle are very alike. Because if you look at their weights you can tell their eating pattern. Small Fry on the other hand eats nothing as well as Teddy bear. They are not like their cousins.

    5)I think the range is spread out because some turtles are eating very little like pancake because maybe they are sick and others are on growth spurts like Bubbles.

    6)I think Yertle will gain 15 grams over the next month. By Dec. 1 he will be 43 grams. And Bowser will gain 15 grams, ending him at 45 grams.

    1) The range for the turtle weights in the Concord schools Alcott, Willard, and Thoreau is 12 grams -37 grams.

    2) The outliers for the weights for the turtles are 33 grams and 37 grams.Bubbles is 37 grams and Ripstick is 33 grams.

    3) The median turtle weight is 22.5 grams.

    4) Small Fry, Teddybear and Quigley are the turtles in the schools that are siblings of Yertle and Bowser. Quigley and Yertle both weigh 28 grams. Teddybear is 15b grams smaller than Bowser. Small Fry is 2 grams smaller than Teddybear.

    5) I think the range is big because some classes might be feeding the turtles a different amount of pellets or food. The turtles also can be eating very little of pellets or food.

    6) I think Yertle and Bowser are going to weigh at least 40 or 50 grams on December 1 because every month we have had the turtles in our classroom they have practically doubled their weight.

  22. 1.The range is from 12 grams to 37 grams.

    2. I think 37 grams might be an outlier.

    3.The median I got was 22 grams

    4. I noticed that 2/3 of Yertle and Bowser’s other siblings are all below 20 grams and Yertle, Bowser, and Quigley are well over that.

    5. Maybe the temperature was different with the 2 turtles with 2033 ID at alcott.

    6. Around 58 grams because they appear to be doubling their weight

  23. Very impressive! I am thrilled to see that you are learning how to analyze the data, make predictions, and communicate your findings. You are not only participating in an real time research project you are also investigating your own questions and making your own predictions in the same manner as how scientist do. I wish I had an opportunity to conduct real scientific research when I was your age. Not only are you helping scientist answer a very important question- How to restore the current population of threatened Blanding’s turtles? You are also gaining the skills needed to make educated decisions about our planet. As you learn and experience more about our natural world you are also gaining the skills and knowledge to share with others. I used to own and operate a Traveling Sea School and kids of all ages used to ask me all the time-“What can I do to help?” I would respond, and still do, “You can help by learning”. By sharing your knowledge you are helping to educate people that everything in nature is connected and everything we do effects the natural world around us. Once again I applaud your efforts with this project and encourage all of you to never stop asking questions – remember- you can all be proud to say that, “I am helping by learning!” I am looking forward to seeing how big the turtles are getting! Keep up the good work- Mrs. K
