Finally, notice that APA-style tables are numbered consecutively starting at 1 (Table 1, Table 2, and so on) and given a brief but clear and descriptive title.

Median (mean) of the median sample size per article for each journal and results of the Wilcoxon test. This is in line with results by LeBel et al. Table 7 gives the results per journal. Write up and analysis . Specifically, we checked whether the sample size described in these articles matched the reported df of the relevant t tests. If you look at the plot on the bottom right, Residuals vs Leverage, you'll see that some of the outliers have some significant leverage as well.Let's say for the sake of example, that we wanted to remove these outliers from our dataset so that we could fit a better . Given that unreported exclusion of data may not always be visible by comparing the dfs and reported sample sizes, it is quite possible that unreported exclusion of data is even more common in psychological research than our current results suggest. You may find that you have new outliers when you do this and these too will need to be dealt with. I have a question that is not necessarily about multiple linear regression. Hey there, sorry for the delay in replying. If they are then the assumption is met and can be reported like this: The data also met the assumption of non-zero variances (IQ Scores, Variance = 122.51; Extroversion, Variance = 15.63; Sales Per Week, Variance = 152407.90). These 108 articles will be inspected further in the current study to see whether there outlier exclusion is related to the strength of the evidence against the null hypothesis, sample sizes, and the number of reporting errors. But I just tell you, thanks for sharing this information and be a good person reducing the effort to others. For this bootstrap procedure we randomly assigned each paper (and all the p values in it) to two groups (removal and no removal) on the basis of the number of articles in each condition, and compared the median p values in the two groups with a Wilcoxon test. (3) When the study is of high quality (i.e., is well designed and sufficiently powered), the original study outcome (without QRPs such as the ad hoc removal of outliers) will more likely be significant. Describing scatterplots (form, direction, strength, outliers) Dont be so quick to forget you were in this position once. Yet another reason to expect a relation between gross errors (i.e., misreporting of outcomes as being significant which appear not to be significant) is that this represents a QRP that has an estimated prevalence of 22% [22]. Once you have conducted your descriptive statistical analyses, you will need to present them to others. Outlier removal and the relation with reporting errors and quality of
