## 2011 Hatchlings By the Number

Now that we have our two new Blanding’s turtle hatchlings, it’s time to reacquaint ourselves with data analysis. Take a look at the following three tables and answer the questions about each. Remember to answer your questions in full sentences. You can click on the tables to make them easier to read. A reminder of data analysis terms:

1. Range: list the data from the lowest number to the highest number.

2. Median: the middle number in a set of data. If it is an odd number of data, it is the middle number. If it is an even number, you add the middle two numbers and divide it by two.

1. What is the range of lengths for the hatchlings of Turtle 3300? What is the difference between the lowest and highest length? What is the median length?

2. What is the range of weights for the hatchlings of Turtle 3300? What is the difference between the lowest and heaviest weight? What is the median weight?

3. Where does our turtle 224 fall within this data?

1. What is the range of lengths for the hatchlings of Turtle 334? What is the difference between the lowest and highest length? What is the median length?

2. What is the range of weights for the hatchlings of Turtle 334? What is the difference between the lowest and heaviest weight? What is the median weight?

3. Where does our turtle 232 fall within this data?

Take a look at the number of hatchlings for both these turtle mothers. How would you describe the number of live births that each turtle mother had in 2011? What would you attribute this difference to?
