We have a mathematical expression for linear regression as below: Don’t get much involved in graphs now we are anyhow going to dig it deep in the second portion of this article. If you plot this information through a chart, let’s see what it gives.Īs the above screenshot shows, the linear relationship can be found in Height and Weight through the graph.

Suppose you have data on the height and weight of 10 individuals. Therefore, we are going to talk about the two methods discussed above only. But why should you go for it when excel does calculations for you? There is actually one more method which is using manual formula’s to calculate linear regression.

There are two basic ways to perform linear regression in excel using: These were some of the pre-requisites before you actually proceed towards regression analysis in excel.

Negative Linear Relationship: When the independent variable increases, the dependent variable decreases.

Positive Linear Relationship: When the independent variable increases, the dependent variable increases too.

There are basically two types of linear relationships as well. Linear relationship means the change in an independent variable(s) causes a change in the dependent variable. This means these are the variables using which response variables can be predicted.

Independent Variable (aka explanatory/predictor variable): Is/are the variable(s) on which response variable is depend.

Dependent Variable (aka response/outcome variable): This is the variable of your interest and wanted to predict based on the Independent variable(s).

Linear regression is a statistical technique that examines the linear relationship between a dependent variable and one or more independent variables.
