Hypothesis Statement There is a negative weak correlation between the amount of minutes spent reading per day and the amount of minutes watching television per day

Polling Tool Polling Tool: The Questions that we asked were “How Many minutes do you spend reading per day?” and “How many minutes do you spend watching television per day?”

Scatter Plot

Line of Best Fit

Calculations Predicted points=(x1=20,y1=175)(x2=40,y2=80) Y=175 M=-95/20 X=20 B=270 Y2-y1 X2-x1 = m

Summary of expected middle school student behavior The more time you spend watching tv, the less time you will read. You could also say that the more time a middle school student spends reading, the less time they will spend watching tv.
