Question

A researcher collects data from 18 people and calculates a Pearson correlation of r = -.42. Assuming  = .05 (two-tailed) , the researcher would make the decision to ______.

A) reject the null hypothesis (p < .05)
B) reject the null hypothesis (p < .01)
C) not reject the null hypothesis (p > .05)
D) not reject the null hypothesis (p < .05)

Celine Miron · Accepted Answer

Final Answer : C, Explanation :  The null hypothesis is that there is no correlation between the variables. Since the p-value (probabilty of obtaining a correlation coefficient as extreme as the one observed assuming the null hypothesis is true) is greater than .05, we fail to reject the null hypothesis. Therefore, we can conclude that there is insufficient evidence to suggest that there is a significant correlation between the variables.
