PEARSON r: INTERPRETATION: I

RIDDLE: What kind of cow gives evaporated milk?

Directions: To find the answer to the riddle, write ‘T’ for “true” or “F” for “false”.

1. ___ A Pearson r of 1.00 represents no relationship. (M)

2. ___ A Pearson r of 0.50, is more likely to be called “moderately strong” than to be called “weak.” (A)

3. ___ A Pearson r of -0.50 is more likely to be called “moderately strong” than to be called “weak.” (D)

4. ___ A Pearson r of -0.97 represents a very weak relationship. (E)

5. ___ A Pearson r indicates both the strength and direction of a relationship. (R)

6. ___ A Pearson r is a type of correlation coefficient. (Y)

7. ___ If a relationship is extremely strong, a Pearson r will have a value greater than 1.00. (I)

8. ___ A Pearson r of 0.95 represents a very strong relationship. (C)

9. ___ The maximum value of a Pearson r is 0.00. (F)

10. ___ The possible values of a Pearson r range from -1.00 to 1.00. (0)

11. ___ The purpose of a Pearson r is to establish the central tendency of a set of scores. (P)

12. ___ All negative relationships are weak. (D)

13. ___ A scatter diagram with dots that form a pattern going from the lower lefthand corner to the upper right-hand corner represents scores that would yield a positive value of r. (W)

14. ___ If a Pearson r between two variables is very strong, this provides very firm evidence that one variable affects the other. (S)
