Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

To determine

Discuss the relationship between the distance from hole and percent of putts made for the sample of professional golfers.

Expert Solution & Answer
Check Mark

Answer to Problem 8E

Negative, strong, curved association with no outliers.

Explanation of Solution

Given information:

For scatterplot:

Horizontal axis: Distance (ft.)

Vertical axis: Percent made

  PRACTICE OF STATISTICS F/AP EXAM, Chapter 3.1, Problem 8E

Strength: In the scatterplot, the points lie very close together in the pattern and there is no strong deviation of points from this general pattern. Thus, strength will be strong.

Form: In the scatterplot, there appears to be a bit of curvature present. Thus, form will be slightly curved.

Direction: Due to the downward slope of the pattern, the direction will be negative.

Unusual features: In the scatterplot, no points in the other scatterplot points significantly deviate from the general pattern. Thus, no outliers exist.
