Independent t-test

The independent t-test is used to compare the means of two groups of different subjects. The videos include how to summarise data and the basics of hypothesis testing which is a useful introduction for those new to statistics. How to check assumptions and how to carry out a Mann-Whitney test if the data are very skewed are also included.

Paired t-test

A paired t-test is used when testing two measurements of the same thing e.g. weight before/after a diet or when each subjects has measurements taken when under different conditions.

Regression

Linear regression allows you to test several independent (explanatory) variables at the same time. Simple linear regression looks at the relationship between one continuous dependent (outcome) variable and one continuous independent variables and multiple regression extends to multiple binary or continuous independents. Watch the simple linear regression video first as it contains more detail.

Cronbachs alpha

Whe using a scale to measure an underlying latent variable e.g. confidence or depression, use Cronbachs alpha to check the items (individual questions) are consistent.
