These ten videos introduce descriptive statistics, then sampling, confidence intervals, and meta-analysis. They explain why estimation and meta-analysis ('The New Statistics') are much better than traditional null hypothesis significance testing (NHST). Enjoy the 'Dance of the p values', which highlights just how unreliable p values are. Confidence intervals are much more informative. There is currently a shift occurring from NHST to The New Statistics. This is a great development, which will lead to improved research progress.
