QUESTION 6

A researcher wants to explore the relationship between the following two variables, Weight 1 and Weight 2.

Suppose that Weight 1 is the weight (in pounds) of a sample of five individuals before beginning a weight-loss diet, and Weight 2 is the weight in (pounds) of the same five individuals after the diet. If we would like to test the effectiveness of the diet, which of the following is the appropriate inference method?

A. matched pairs

B. two independent samples

C. inference for regression

A. matched pairs

B. two independent samples

C. inference for regression

Explanation / Answer

Weight 1 is the weight (in pounds) of a sample of five individuals before beginning a weight-loss diet, and Weight 2 is the weight in (pounds) of the same five individuals after the diet.

Here before and afer weightloss is dependent variable.

Hence we can use matched pairs.

SInce both are independent variables.
