Question

When conducting correlation analysis, what's the first thing you do?

a. Look at the data plotted in a scatter diagram to see if it looks like there's a relationship between the two variables

b. Look at the data plotted in a scatter diagram to see what it looks like the nature of the relationship between the two variables is

c. Check the assumption - are the data normally distributed?

d. Create a cause-and-effect diagram

Answer 1

The first step in conducting correlation analysis is to decide which variable is the independent and dependent variable. Then, draw a scatter plot to visually inspect the relationship between the variables.

Step-by-step explanation:

a. The first step in conducting correlation analysis is to decide which variable should be the independent variable and which should be the dependent variable.

b. After deciding, you can draw a scatter plot to visually inspect if there is a relationship between the variables.

c. From the scatter plot, you can determine the nature of the relationship, whether it is linear or not.
