A school nurse records the age and height of each student she sees in a week. Then she makes a scatter plot showing the ages of students (in years) on the x-axis and their heights (in centimeters) on the y-axis. 1. The red dot has the coordinates (5, 105). What do you know about the student represented by this point? 2. Based on the graph, how do you think age and height are related? Gizmo Warm-up Because we grow as we get older, a scatter plot of height vs. age will show that older children are generally taller than younger children. When two variables are related, like age and height, they are said to be correlated. The Trends in Scatter Plots Gizmo explores different types of correlation. To begin, check that the slider is close to the Positive trend side. 1. When there is a positive trend (or positive correlation), do the y-values of the points on the scatter plot
