The Survey Data Analysis Plan

  1. Step 1: Calculate simple statistics (mean, max, etc.)
  2. Step 2: Graph Each Question and Add Error Bars.
  3. Step 3: Add Histograms of Each Question.
  4. Step 4: Plot Averages Over Time, with Error Bars.
  5. Step 5: Test for Significant Differences with Student’s t-Test.

Why is ANOVA more powerful than T-test?

Why not compare groups with multiple t-tests? Every time you conduct a t-test there is a chance that you will make a Type I error. An ANOVA controls for these errors so that the Type I error remains at 5\% and you can be more confident that any statistically significant result you find is not just running lots of tests.

Why is ANOVA test good?

ANOVA is helpful for testing three or more variables. It is similar to multiple two-sample t-tests. However, it results in fewer type I errors and is appropriate for a range of issues. ANOVA groups differences by comparing the means of each group and includes spreading out the variance into diverse sources.
