Question

Observe the data set called Teachers Pay (see attached two pages). The variable Pay represents the mean annual salary for teachers by state in 1995 and the variable Spend is the per pupil spending by state in 1995. Both of these variables are in thousands of dollars. For example Maine (ME) paid their teachers a mean salary of $32,000 in 1995 and spent $6410 per pupil. Make a scatterplot using Spend as the explanatory variable (you do not have to turn in the scatterplot).

State the form of the scatterplot:______________.

Answer 1

A scatter plot is a graph that displays the relationship between two variables. In this case, the scatter plot will show the relationship between per pupil spending and mean annual salary for teachers by state in 1995.

Step-by-step explanation:

A scatter plot is a graph that displays the relationship between two variables. In this case, the scatter plot will show the relationship between per pupil spending and mean annual salary for teachers by state in 1995. The explanatory variable (x-axis) is Spend (per pupil spending) and the response variable (y-axis) is Pay (mean annual salary for teachers).

The form of the scatterplot can be determined by observing the pattern of the points on the graph. It could be linear, meaning the points form a straight line, or it could have a curvilinear form, meaning the points form a curved pattern. This can be determined by visually inspecting the scatterplot.
