Scatter Plots

The scatter plot below shows the number of books read by students in Mrs. Hall’s English class and their final grades. Which statement represents the best description about the line of best fit?

• The more books students read, the lower their English grade.

• The more books students read, the higher their English grade.

• The fewer books students read, the higher their English grade. 

• No relationship exists between the number of books students read and their English grades.

A trucking company keeps track of the number of miles each of its drivers logs each week.  Describe the correlation between the number of miles a driver logs and the drivers age.

• There is a positive correlation.

• There is a negative correlation.

• There is no correlation.

• There is a parallel correlation

In a scatterplot, an outlier...

• ...is something we didn't learn 8th grade

• ...is a puppet with a long nose named Pinocchio

• ...is a point that is far outside the main cluster of points/ordered pairs

• ...is a really naughty point who doesn't tell the truth when outside

If a scatterplot has no association then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)

Find the equation of the line of best fit for the given data

• y=163.41x + 4.19

• y=-163.41x + 4.19

• y=-4.19x + 163.41

• y= 4.19x - 163.41
  

Which scatter plot shows a linear relationship between x and y?

• Graph A

• Graph B

• Graph C

• Graph D

You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?

• As x increases, y decreases

• As x increases, y increases
