Weight = 0.6746*Height вЂ“ 38.45508 (Slope value for Height is 0.6746вЂ¦ and Intercept is -38.45508вЂ¦)Дid you get what you have defined? You have defined a function in which you now just have to put the value of Height, and youвЂ™ll get the Weight value. Now our, regression equation for prediction becomes: It gives values of coefficients that can be used to build the model for future predictions. The other important part of the entire output is a table of coefficients. Or in another language, information about the Y variable is explained 95.47% by the X variable. In this case, the R Square value is 0.9547, which interprets that the model has a 95.47% accuracy (good fit). One important part of this entire output is R Square/ Adjusted R Square under the SUMMARY OUTPUT table, which provides information, how good our model is fit. However, interpreting this output and make valuable insights from it is a tricky task. Till here, it was easy and not that logical. Excel will compute Regression analysis for you in a fraction of seconds.Under the Normal Probability option, you can select Normal Probability Plots, which can help you check the normality of predictors.In this case, check the Residuals checkbox so that we can see the dispersion between predicted and actual values.

Under the Residuals option, you have optional inputs like Residuals, Residual Plots, Standardized Residuals, Line Fit Plots which you can select as per your need.

In this case, we want to see the output on the same sheet.

Under Output options, you can customize where you want to see the regression analysis output in Excel.

The confidence level is set to 95% by default, which can be changed as per users requirements.

Check the box named Labels if your data have column names (in this example, we have column names).

Input X Range: Select the cells which contain your independent variable (in this example, A1:A11).

Input Y Range: Select the cells which contain your dependent variable (in this example, B1:B11).

Use the following inputs under the Regression pane, which opens up.

In the excel spreadsheet, click on Data Analysis (present under Analysis Group) under Data.

But why should you go for it when excel does calculations for you?

There is actually one more method which is using manual formulaвЂ™s to calculate linear regression.

Regression tool through Analysis ToolPak.

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).
