Question

Amanda conducts a study and gets a correlation of -.87, p=.01. Amanda should conclude:

a) A strong, positive and significant relationship.
b) A strong, negative, and significant relationship.
c) A weak, positive, and nonsignificant relationship.
d) A weak, negative, and nonsignificant relationship.

Answer 1

The correlation coefficient is -0.87, indicating a strong negative relationship. The p-value of 0.01 shows it is significant. Amanda should conclude a strong, negative, and significant relationship.

Step-by-step explanation:

The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient is -0.87, which indicates a strong negative relationship. The p-value of 0.01 indicates that this correlation is significant, meaning that it is unlikely to have occurred by chance. Therefore, Amanda should conclude that there is a strong, negative, and significant relationship between the variables she studied.
