Does Height affect Shoe Size? By: Ms. Cooper Block 2 March 23rd, 2018

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

Response Data Ages surveyed: 13, 14, 15, and 12 Height range: 49-70 inches Number of girls surveyed: 10 Number of boys surveyed: 10

Scatterplot

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.

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.
