A two-way repeated measures ANOVA goes further than a one-way repeated measures ANOVA, which only has one factor (i.e., one independent variable). For example, a one-way repeated measures ANOVA could be used when you only wanted to know whether there was a difference in chronic back ...
Or maybe you're deep in conversation with a friend and you suddenly get the feeling that you've had the exact conversation before, even though you know that you haven't. If you've ever found yourself in either of these situations, you've experienced déjà vu. Sixty to 70 percent of ...

Now, we begin to ask individuals, “When this happens to you, what do you do or what have you done?” And we came out with literally hundreds of different actions that can be taken. The problem was that there was no organization. We began to do what we called a secondary factor ...
Due to the lack of multivariate normality, the Bollen-Stine bootstrap p procedure (performed 5000 times) was used to correct for fit statistic bias [36,37,38,39,40]. The following parameters were used to assess model fitness: relative chi-square (χ2/df), goodness of fit index (GFI),...
At the same time, many more people are still joining from home or other locations, desperate to be included but unable (or unwilling) to attend a live event in-person. What everyone wants is to get back to some semblance of normality. But this new reality brings new challenges that event...
The visual approaches perform better than statistical tests. For example, the Shapiro-Wilk test has low power for small sample size data and deviates significantly from normality for large sample sizes (say n > 50). For large sample sizes, you should consider to use QQ-plot for normality assu...
Choose NORMALITY TEST Type your data column in the VARIABLE BOX (do not fill in the reference box) Choose RYAN JOINER (this is the same as Shapiro-Wilk) Click OK R:Although not as popular as SPSS or Excel, R does have the ability to perform the test. The argument is very simple: ...
We began to do what we called a secondary factor analysis. We grouped all the antibias strategies that were similar into categories, and we came up with four different categories in which microinterventions fell into. The first category was to make the invisible visible. As long as you’re ...
Should I try further transforming the data (e.g., log, logit, arcsine) with the hope that the distribution will more closely resemble normality? Or should I leave the data as-is and abandon the idea that I will be able to interpret the final index's comparative u...
