To predict one variable from another,you must first ______.
A) compute the mean
B) compute the standard deviation
C) compute the correlation
D) compute the variance
Compute Correlation
The process of determining the degree to which two variables are related or move together, often measured by correlation coefficients such as Pearson's r.
Standard Deviation
The average amount of variability in a set of scores or the scores’ average deviation from the mean.
Compute Mean
The process of calculating the arithmetic average of a set of numbers by summing them up and dividing by the count of numbers.

Final Answer :
C
Explanation :
To predict one variable from another, you would need to calculate the correlation between the two variables to see if they are related and to what extent. The mean, standard deviation, and variance are all measures of central tendency and variability, but they do not give you information about the relationship between two variables.
