Regression is a complex statistical technique that tries to predict the value of an outcome or dependent variable, such as annual income, economic output or student test scores, based on one or more predictor variables, such as years of experience, national unemployment rates or student course gra...
Interpret the N values as the number of samples tested in each of the two groups for the t-test. For example, comparing the cholesterol levels of 100 men and 100 women would have two N values of 100 and 100, respectively. Find the standard deviation values and relate them to the data ...
In the case of pre-post treatment-control design, this is often the effect of greatest interest. It is relevant to assessing whether the effect of time varies between groups. For example, if it is statistically significant you would then look at the direction of the s...

Learn, step-by-step with screenshots, how to run a multinomial logistic regression in SPSS Statistics including learning about the assumptions and how to interpret the output.
This post mentions the package and refers to the vignette. Thanks for the advice! Up-date 2023/10/11 As suggested by Frank Harell I computed the ordinal (logistic) regression with the orm function from rms. This gives me values, but I am not clear how to correctly interpret ...
Learn, step-by-step with screenshots, how to run a principal components analysis (PCA) in SPSS Statistics including learning about the assumptions and how to interpret the output.
In the subsequent regression model, you estimate the post treatment score as a linear function of pre treatment score and being in the treatment group whey or the treatment group casein. Because the control group is left as the reference category for the dummy variables, you...
