Fill in the blanks using the following words:  Outlier,  Positive, Scatter Plot, Negative

If the points are going diagonally up from the left of the graph and looks like there is a line, the scatter plot is forming a

correlation.

Use the sentence frames below to answer the prompt.

I have found that positive correlation looks like _____________________, because ________________________________________________________.

I have found that negative correlation looks like _______________________, because __________________________________________________________________.

Outliers are ________________________________________________________.

Fill in the Blanks

The table shows the number of stories, x, and the heights, y, in meters, of 6 buildings.

The data in the table are fit to a linear model. The equation of the model is y=5.18x-81.67.

 

Based on the equation, what is the expected height, in meters, of a building with 60 stories?
