Question
Question 9 Marks: 1 A researcher wants to predict attitude towardhuman rights from years of education. Attitude towards human rightsis measured on a scale of 0-100. Years of education ranges from 9to 30.He reports the following data:
slope = 2
t (slope) = 9.2
P(test of slope) = 0.000
R^2 = 2%
What is the best answer?
Choose one answer. a. He should conclude that yearsof education is a staitically signiciant but practicallyinsignificant predictor of attitude towards humanrights. b. He should conclude that yearsof education is a statistically and practically significantpredictor of attitudes toward human right. c. He can conclude that years ofeducation is a statisticaly significant predictor of attutudetowards human rights becasue he has the P value for the slope, but,since he does not have the P value for R^2 we cannot judge thepractical significance. d. He should conclude that yearsof education is neither a statistically signficant and nor apractically significant predictor of attitude towards humanrights.

Explanation / Answer
Since p is so small, we know that years of education isstatistically significant (i.e. the coefficient for this variableis not 0). However, your R^2 is very small. This could mean a fewdifferent things. 1) Your sample was all of people who are approximately the sameage. Thus, the effects of the change in age were obscured bythe change in other factors. 2) There are many other variables that are changing simultaneouslyand you are only measuring 1 which appears to have only a smalleffect relatively speaking. Thus, I would say A or B (where A seems far more likely). C is wrong because you don't obtain p values for R^2. D is wrong because the variable is clearly statisticallysignificant because of the small pvalue.
