Part IA 1 . A maximum linear correlation is expressed as: a. 100% b. 99 +10 . 00 d. $1. 00 2. The more a correlation deviates from zero, : a . the more it is certain to be positive in sign b . the more it is certain to be negative in sign C. the more it is certain that the measured variables are independent of each other d . the better its predictive accuracy When two sets of measures are independent of each other, then the correlation between them must be: a. negative b. positive zero d. can't be determined 4 . Of the following correlation coefficients, which expresses the weakest association? a . 10 b . -. 20 C . - . 50 . -1 .00 5. When two variables, A and B, are strongly correlated, it means that: a. A has caused B b. B has caused A C . some third variable has caused both A and B to occur together none of these 6. The correlation coefficient, in and of itself, : a, never proves causation b. never rules out causation c. allows for better-than-chance predictions d . all of these 7. The originator of the product-moment correlation technique was : a. Gauss b. Pascal C . Pearson d. Spearman 8. The correlation between parental income and the amount of financial aid awarded by the college to students should most probably be : a. positive b. negative c. zero d. none of these 9 . Among elementary school children, the correlation between age and height would most probably be: positive b. negative c. zero d. non- linear 10. A "significant correlation" is one which: a . is especially meaningful b . does not deviate from zero c . indicates a valid difference . can be generalized to the population
