So, the umbrella is a dependent variable whose sell depends on the rainfall percentage of each month, which is an independent variable. This Excel worksheet will contain three columns: Months (Jan to Dec), Rainfall percentage, and sold umbrella quantity (total number of umbrellas sold in each month). Umbrellas are most sold in month July and less sold in January. Each month sell is different according to rainfall. This data is for the sell of umbrellas from January to December. Let's take a scenario to understand the variables of regression analysis -įor example, we have sells data of 12 months stored in an Excel worksheet. In contrast, independent variables are those factors that affect the dependent variable and helps to predict the value for dependent variables. The value of dependent varies according the independent variable. Independent variable (explanatory variable)ĭependent variable is the factor that we try to understand and predict.Dependent variable (predictor variable).Note: Independent and dependent variable are the two most essential terms of regression analysis. The variable that is being described is called dependent variable, while the variable, which is used to describe or predict the value of dependent variable is called independent variable. In simple linear regression, the value of one variable is used to describe the value of another variable. This equation consists of a coefficient that represents the relationship of dependent and independent variables. Regression analysis is an analysis that shows a relationship between dependent and independent variables and produces an equation.
We will explain all these terms in this chapter. It is available in the Add-ins.īefore going in deep, you must know - what is regression analysis? Types of variables in it and many more basics things.

Note: Excel users do not need to install the Data Analysis ToolPak from the internet. You have to add this Data Analysis ToolPak exclusively to your Excel from Add-ins. In MS Excel, regression feature is available at the end inside the Data tab. This one is a good option because almost every computer user can access Excel.Įxcel provides the inbuilt method to calculate the regression. In MS Excel, you can perform several statistical analyses, including regression analysis. The regression analysis is a part of statistical modeling that is used to estimate the relationship between the two or more variables. Next → ← prev Regression analysis in Excel
