This activity uses real life data to help students practice plotting data points, linear regression, correlation coefficients, and different types of correlation. Students love getting to guess the ages of famous celebrities!
The teacher passes out the student handout and shows the pictures one at a time of the 10 celebrities.Students record their guess of the celebrity’s age on their handout. At the end of the slide show, students are shown the birthdays of the celebrities and have to calculate their actual ages.
Students then follow the directions on the handout which requires them to plot their data, draw a line of best fit, find the correlation coefficient, identify the type of correlation, and find the line of best fit.
