2.11 Comparing two groups using a statistical test : numerical data
- Example: comparing moderate-to-vigorous physical activity which was measured using an accelerometer (
MVPA_acc) between 2 groups of Walkability - We assume data are independent: Seniors were selected independently from each other and for each senior, the walkability of the neighborhoud was measured.
BEPAS Comparing two groups: numerical data using a statistical test
The tables below are discussed in the video “Comparing 2 groups” at the Ufora website.
The example in the video is about comparing BMI between two groups of walkability (“Low walkability” and “High walkability”). We will first compare physical activity between two groups.
Unpaired tests for independent data:
Paired tests for dependent data:
