A researcher collects data from 25 people and calculates a Pearson correlation of r = .38. 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)
Pearson Correlation
A measure of linear correlation between two variables, ranging from -1 to 1, where 1 means a perfect positive linear relationship, -1 means a perfect negative linear relationship, and 0 indicates no linear relationship.
- Interpret the significance of correlation coefficients in research contexts.
- Employ critical values for making informed decisions in hypothesis testing concerning correlation analyses.

Final Answer :
C
Explanation :
The researcher would not reject the null hypothesis (p > .05) because the p-value is not less than .05. Therefore, there is not enough evidence to conclude that there is a significant correlation between the variables.
