2. Survey Questions and Variables
- independent variable: height
- dependent variable: shoe size in inches
Survey Questions:
What is your height?
What is your shoe size?

3. Response Data Ages surveyed: 13, 14, 15, and 12
Height range: inches
Number of girls surveyed: 10
Number of boys surveyed: 10

4. Scatterplot

5. Line of Best Fit
y = 3.33x + 30
Y= 3.3x +30

6. Scatterplot- No Correlation example
There was no correlation of the data because there was a wide variety of responses for people in the same age group.
I could have asked about age and height to see if there was a more easily defined correlation between those two variables.

7. Reflection - Height and Shoe size
There is a positive correlation between height and shoe size. This means that typically, taller people could have larger feet.
To make this survey more valid, I would have chosen a more random sample across different age groups
This applies to my life because I can predict how large my feet may get as I grow.
