RIDDLE: What kind of cow gives evaporated milk?

DIRECTIONS: To find the answer to the riddle, write "T" for "true" or "F" for "false" on the line next to each
statement. The letter at the end of the first true statement is the first letter in the answer, the letter at the end of
the second true statement is the second letter in the answer, and so on.

_____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 -.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 very 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. ©

_____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. (O)

_____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 left-hand corner to the upper

right-hand corner represents scores that would yield a positive correlation. (W)

_____14. If a Pearson __r__ between two variables is very strong, this provides evidence that one variable effects

the other. (S)
