Mean and Variance of Normal Distribution
Calculus/Probability: We calculate the mean and variance for normal distributions. We also verify the probability density function property using the assumption that the improper integral of exp(-x^2) over the real line equals sqrt(pi).

Levene’s Test of Homogeneity of Variance in SPSS (11-3)
One important assumption about the Independent-Samples t Test is that the variances in the sample groups are approximately equal. We assume that the samples have “homogeneity of variance.” Levene’s Test for Equality of Variances is a test of whether the variances of the two samples/groups

How to find the variance and standard deviation from a set of data
👉 Learn how to find the variance and standard deviation of a set of data. The variance of a set of data is a measure of spread/variation which measures how far a set of numbers is spread out from their average value. The standard deviation of a set of data is a measure of spread/variation

One Way ANOVA in Business Statistics, How and Why we Need ANOVA
The One-Way ANOVA allows us to extend the independent samples t-test for use with three or more groups. Instead of comparing means (like a t test), we analyze the variance between and within the groups. If the ANOVA is significant, we then follow up with a post hoc test to determine what d
