In the Add-Ins available box, select the Analysis ToolPak check box, and then click OK.In the Manage box, select Excel Add-ins and then click Go.Click the File tab, click Options, and then click the Add-Ins category.These instructions apply to Excel 2010, Excel 2013 and Excel 2016. if the Data Analysis command is not available in your version of Excel, you need to load the Analysis ToolPakadd-in program. You can use the Data Analysis Add-in to run a regression in Excel. Here, bi’s (i=1,2…n) are the regression coefficients, which represent the value at which the criterion variable changes when the predictor variable changes. The multiple regression equation is y = b1x1 + b2x2 + … + bnxn + c. The variable we want to predict is called the dependent variable (or sometimes, the outcome, target or criterion variable) It is used when we want to predict the value of a variable based on the value of two or more other variables. Multiple regression is an extension of simple linear regression. Click here to download this practice file. Below is the steps to run the regression in Excel.We will start with determining the P-value for tail 1 or in one direction. In this section, we will be using the T.TEST function to determine the P values for tails 1 and 2. Method-2: Using T.TEST Function to Calculate P Value in Linear Regression in Excel Moreover, we can see that for the Alpha value of 0.05 we are getting the P values less than 0.05 which means it neglects the null hypothesis and so the data is highly significant. Because the two-tail P-value considers both the increase and decrease of the marks whereas the one-tail P-value considers only one of these cases. We can see the one-tail P-value is half times the two-tail P-value. ➤ You can change the value for Alpha from 0.05 (automatically generated) to 0.01 because the designated value for this constant is generally 0.05 or 0.01.Īfter that, you will get the P-value for two cases the one-tail value is 0.00059568 and the two-tail value is 0.0011913. ➤ As Input we have to provide two variable ranges $C$4:$C$11 for Variable 1 Range and $D$4:$D$11 for Variable 2 Range, as Output Range we have selected $E$4. ➤ Select the option t-Test: Paired Two Sample for Means from different options of Analysis Tools.Īfter that, the t-Test: Paired Two Sample for Means dialog box will open up. Then, the Data Analysis wizard will appear. ➤ Now, go to the Data Tab > Analysis Group > Data Analysis Option. ➤ Check the Analysis ToolPak option and press OK. ➤ Choose the Excel Add-ins option in the Manage box and then press Go.Īfterward, the Add-ins dialog box will pop up. ➤ Select the Add-ins option on the left panel. If you didn’t activate the data analysis tool then first enable this toolpak at first.Īfter that, the Excel Options dialog box will appear. Here, we will use the analysis toolpak containing the t-Test analysis tool to determine the P-value for these two sets of sales data. Method-1: Using ‘t-Test Analysis Tool’ to Calculate P Value We have used Microsoft Office 365 version here, you can use any other versions according to your convenience. The null hypothesis reckons there is no difference between the two types of sales values and the alternative hypothesis will consider differences between these two sets of values. We will compare these sales values and determine the probability value and then we will determine if P supports the null hypothesis or the alternative hypothesis. Here, we have some predicted sales values and actual sales values of some of the products of a company. Related Articles How to Calculate P Value in Linear Regression in Excel: 3 Ways
