3. Run Statistical Tests
- T-Tests: Use this test to compare the means of two groups. For example, you might compare test scores between two classes.
- ANOVA: Use this to compare means across three or more groups, such as comparing sales in different regions.
4. Create Visuals
- You can generate charts and graphs to better understand and communicate your data.
- Go to “Graphs” > “Legacy Dialogs” > “Bar” or “Pie” to create visual representations of your data.
