## Question

###### Correlation

Three data sets are collected, and the correlation coefficient is computed in each case. The variables are:

1) grade point average in freshman year and in sophomore year

2) grade point average in freshman year and in senior year

3) Lenght and weight of two-by-four boards

Possible values for correlation coefficient are:

-0.50 0.0 0.30 0.60 0.95

Match the correlations with the data sets; two will be left over. Explain your choices

## Answers

1) grade point average in freshman year and in sophomore year: 0.60

2) grade point average in freshman year and in senior year: 0.30

3) Lenght and weight of two-by-four boards: 0.95

all of these should have some sort of positive correlation, so that leaves out -0.50 and 0.0

3) is the result of a manufacturing process so should have a very high correlation

1) should be stronger than 2)
