The Assumption of NORMALITY in Parametric Hypothesis Tests (16-6)
Parametric statistical tests require normality, which does not mean what many people think it means. I explain the true meaning of the assumption of normality, using Stats Blocks, and how to test this assumption with graphs or tests, such as Kolmogorov-Smirnov Test. The Central Limit Theor

Chi Square Test: Interpretation of (O-E)^2/E
In this video, I try to show how the (O-E)^2/E calculation in a chi-squared test is connected the sum of squared z-scores, something visually closer to the definition of a chi-squared distribution. The video should be understandable to new students of stats and more advanced ones.

Welcome to the final lesson on the normal distribution for Year 13. The focus for the last subchapter is explaining that, if a random variable is normally distributed, then so will be the distribution of its sample mean. The sample mean can be used in normal hypothesis tests, as can the no

Using normal distribution to find the probability
👉 Learn how to find probability from a normal distribution curve. A set of data are said to be normally distributed if the set of data is symmetrical about the mean. The shape of a normal distribution curve is bell-shaped. The normal distribution curve is such that the mean is at the cente
