![]() Models using more than one explanatory variable are called multiple regression models. However most models will try multiple variables to better explain the response variable. Then a linear regression will done on the converted data, obtaining its p-value etc. Once Data Analysis has been 'turned on', you will find the data analysis group there. Excel comes with a statistical analysis toolkit that can be found under the data tab. Models built using one explanatory variable are called simple linear regression models. This video demonstrates building a simple linear regression model with Excel and explains how to interpet key outputs that Excel generates. While the variable being explain is called the dependent or response variable. Next, you select the Analysis ToolPak option on the dialog box that appears and click the OK button. The variable being used to explain another variable is known as the independent or explanatory variable. This is done by selecting Office Button > Excel Options > Add-Ins in Excel 2007 or File > HelpOptions > Add-Ins in versions of Excel starting with Excel 2010, and clicking the Go button at the bottom of the window. If the model fits the data well it can be used to predict values of y that can be expected based on values of x. ![]() Advertisement Specifying the correct model is an iterative process where you fit a model, check the results, and possibly modify it. In the Data Analysis popup, choose Regression, and then follow the steps below. What is Linear Regression?īriefly, linear regression is the statistical process of constructing a model to explain the degree to which one variable's change (x) can be used to explain another variable's change (y). In Excel, click Data Analysis on the Data tab, as shown above. The video below demonstrates one of the tools in the Data Analysis Toolpak, common statistical tools - linear regression. Data Analysis Toolpak is an Excel add-in with many statistical tools. Once Data Analysis has been "turned on", you will find the data analysis group there. This video demonstrates building a simple linear regression model with Excel and explains how to interpet key outputs that Excel generates. Joseph Schmuller teaches you how to use the tools in Microsoft Excel. ![]() In the Add-Ins dialog box, tick the Analysis ToolPak check box, then click OK. This course, part two of a series, continues your training on the fundamentals of descriptive and inferential statistics.
