People who deal with raw data are also looking for an analysis of these data. People such as graduate students, university professors, and researchers from research institutes are those who need to have an analysis of these data. Statistical tests or regression are some of them. The tutorial teaches you how to determine regression in excel.

What is regression?

Regression means return. It means predicting and expressing changes of a variable based on other variable information. One of the most widely used in statistics is Regression. Using Regression, one can determine which factors have a great effect on the phenomena. For example, suppose that our dependent variable is the student’s blood pressure, and the independent variable is salt and weight. The question is that salt intake has a greater effect on blood pressure or body weight. We use regression to decide on this.

If you need labels to make headlines clear, click Labels.

In the Output options section, select the destination cell of the Output Range field. Finally, click OK.

The work output is as follows; note the P-value for the two groups Weight and Salt.

As you can see, the P value for the independent salt variable is much smaller than 0.05. It means that there is a distinctive correlation between blood pressure and salt intake. Whereas in the case of a weight variable, this number is greater than 0.05, which is means its low effect on blood pressure.
