Histograms & Frequency Polygons

In this video I explain the difference between histograms and bar charts, look at the creation of histograms and frequency polygons for continuous variables, and then discuss why we want to get a sense of the shape of a distribution of scores in order to compare it to a known distribution such as a normal distribution.

Hii really amazing video . I have a request can u explain p value and test of significance in a video or probably suggest an article ? I’m kinda stuck on it and don’t know where to look for an explanation

[@PsychExamReview]

Yes, I'll definitely get to covering p-values in this series and will have several videos related to significance testing. If you let me know what you're stuck on I might be able to explain it here, since it may be a little while before I get to a video on this. I do have an older video introducing the general concept of significance and p-values that might be helpful, though it doesn't go into detail and is intended more for an intro psych class rather than a statistics course: kzbin.info/www/bejne/aaOZooWii71gnqcsi=bYZWk97PYlb6hK0B
