Description

Includes two versions for high school statistics standards, including graphing data, analyzing the association, finding a line of best fit/linear regression, interpreting slope, calculating a correlation coefficient, and more!

Students will guess celebrity ages, then use the data from their guesses and the actual ages to create a scatterplot and interpret the information it provides.

Answer keys included!

Choose which version will work best for your students:

Version 1: Best for high school students with more experience with scatterplots and writing equations of lines. Students will set up a scatterplot, collect data, plot points, analyze its association, draw and find the equation of a trendline, and interpret the slope and y-intercept. No technology is needed.

Version 2: Best for high school students with experience using technology to calculate a linear regression and correlation coefficient. Students will set up a scatterplot, collect data, use technology to calculate the linear regression line and correlation coefficient, and interpret the slope, y-intercept, and correlation coefficient.

**You will need to create a list of current, relevant celebrities and their ages to use this activity. Celebrity ages are very easy to find with a quick Google Search.**
