SPSS output usually looks terrible. However, it doesn’t have to: you can manually style your tables and charts in the output window. The styles you apply such as colors, borders and fonts can be saved as SPSS chart templates and SPSS table templates. These can easily be reapplied to future output. A little known trick -but a real life saver […]
COMPUTE v2 = RANGE(V1,2,4). SPSS RANGE Function Result Summary SPSS’ RANGE function is used to evaluate whether or not values are within a given range. Test values equal to the lower or upper boundary are also within the given range. Run the syntax below for a quick demonstration. SPSS Range Syntax Example *1.

“I have a data file on which I’d like to carry out several regression analyses. I have four dependent variables, v1 through v4. The independent variables (v5 through v14) are the same for all analyses. How can I carry out these four analyses in an efficient way that would also work for 100 dependent variables?” […]
A magazine wants to improve their customer satisfaction. They surveyed some readers on their overall satisfaction as well as satisfaction with some quality aspects. Their basic question is“which aspects have most impact on customer satisfaction? ”We’ll try to answer this question with regression analysis. Overall satisfaction is our dependent variable (or criterion) and the quality […]

Our data basically just hold job performance scores and IQ, motivation and social support which -supposedly- contribute to job performance. The meaning of our variables is seen under variable view, […]
Running a basic multiple regression analysis in SPSS is simple. For a thorough analysis, however, we want to make sure we satisfy the main assumptions, which are linearity: each predictor has a linear relation with our outcome variable; normality: the prediction errors are normally distributed in the population; homoscedasticity: the variance of the errors is constant in the population. […]
Correlation B Coefficients Intercept Regression Residuals R-Square Simple linear regression is a technique that predicts a metric variable from a linear relation with another metric variable.Remember that “metric variables” refers to variables measured at interval or ratio level. The point here is that calculations -like addition and subtraction- are meaningful on metric variables (“salary” or […]
