Your scatterplot:

asked 2021-03-02

1) In what way is the point unusual? Does it have high leverage, a large residual, or both?

2) Do you think that point is an influential point?

3) If that point were removed, would the correlation be- come stronger or weaker? Explain.

4) If that point were removed, would the slope of the re- gression line increase or decrease? Explain

In this exercise, you will use the correlation and regression applet to create scatter plots with 10 points that have a correlation close to 0.7. The lesson here is that many models may have the same correlation. Always compile your data before trusting correlations. (a) Stop after adding the first two points. What is the value of correlation?

(Enter your answer, rounded to four decimal places).

r=?

Why does correlation matter? Two is the minimum number of data points required to calculate the correlation. This value is the default correlation.

Because two points define a line, correlation always matters.

The mean of these two values always has this value.
