Question

Which of the following statement(s) is (are) an important consideration(s) in applying liner regression techniques?

a. the relationship should be linear
b. both variables must be measured in the same units
c. predictions for Y should be within the range of the Xx variable in the sample
d. all of the above
e. a and c

Answer 1

The important considerations in applying linear regression techniques are that the relationship should be linear, and predictions for Y should be within the range of the X variable in the sample.

Step-by-step explanation:

The important considerations in applying linear regression techniques are:

1. a. The relationship should be linear: In linear regression, the relationship between the independent variable (X) and dependent variable (Y) should be linear.
2. c. Predictions for Y should be within the range of the X variable in the sample: When using linear regression to make predictions for Y, the predicted values should fall within the range of X values in the sample.

Therefore, the correct answer is (e) a and c.
