## I Know the Secret to Happiness

It may not be the secret to great joy but it is certainly the secret to avoiding unhappiness and it is simply this: The absence of self-ruminative thoughts. I’d like to claim the idea was originally mine but the truth is I first heard this phrase over a decade ago in a talk by Albert Bandura…

## MANOVA, finally

So, after three posts of recoding, creating scales, checking reliability and distributional assumptions we have arrived at MANOVA.  If you skipped those three posts, feel shame at trying to take shortcuts, go back and read them. Before we dive into coding, let’s take a look at some basic background on MANOVA. The difference between ANOVA…

## MANOVA from beginning to end: Reliability

Where is the Multivariate Analysis of Variance ? You promised there would be MANOVA ! Now we’re in the third post! First there was recoding of variables. Then, there was creating scales.  Now, we’re looking at reliability. Patience is a virtue. Before we get to doing a MANOVA we want to be sure that our…

## MANOVA from beginning to end : Creating the scales

Last time, we saw how to recode variables to score answers correct or incorrect, on a rating scale and weighted by importance. Today, we’re going to look at creating some scales from those variables because for reasons I’m sure I have written about at some point in the past, single items are usually not very…

## MANOVA beginning to end: Recoding Data is Part of the Process

So, I have been doing a few videos here and there to refresh, for example, what is a repeated measures ANOVA and why you might want to do it.   Sometimes I…
