Standardizationis the process of putting different variables on the same scale. Inregression analysis, there are some scenarios where it is crucial to standardize your independent variables or risk obtaining misleading results. In this blog post, I show when and why you need to standardize your var...
Learn how regression analysis can help analyze research questions and assess relationships between variables.
Then, I’ll cover statistical and non-statistical approaches for identifying the most important independent variables in your linear regression model. I’ll also include an example regression model where we’ll try these methods out. Related post:When Should I Use Regression Analysis? Do NotAssociat...

under SPSS Tools & Regression Categorical variables can't readily be used as predictors in multiple regression analysis. They must be split up into dichotomous variables known as “dummy variables”. This tutorial offers a simple tool for creating them....
Secondly, based on multiple regression analysis, this paper proofs that there exists the statistically significant relationship of poultry meat production on export and import of that kind of meat, all measured in kg/capita. There is also a high correlation between production, as a dependent, and...
By entering "1"s and "0"s into your dummy variables in this manner, you will have created a set of dummy variables that you can enter into a multiple regression analysis. In the Procedure section that follows, we show you how to create these dummy variables using the Create Dummy ...
