Bob and Teresa each collect their own samples to test the same hypothesis. Bob’s p-value turns out to be 0.05, and Teresa’s turns out to be 0.01.
Why don’t Bob and Teresa get the same p-values?
Who has stronger evidence against the null hypothesis: Bob or Teresa?
Review a classmate's Main Post.
1. State if you agree or disagree with the choices made for additional analysis
that can be done beyond the frequency table.
2. Choose a measure of central tendency (mean, median, mode) that you
would like to compute with the data beyond the frequency table. Complete
either a or b below.
a. Explain how that analysis can help you understand the data better.
b. If you are currently unable to do that analysis, what do you think you
could do to make it possible? If you do not think you can do
anything, explain why it is not possible.
