How to get the confidence interval (CI ) and to make t-test with multi distributions in one histogram (as direct input data)?

Created: Jan 25, 2022 10:24 AM  |  Last Modified: Jun 10, 2023 07:43 PM (1107 views)

Input data is already the histogram in %.  There are 5 samples in total. Each sample include 2 distributions (bottom and top position). The goal is to calculate the difference between the 2 means (physically, it´s an height). Raw data (´´CI_t test_data_Q12345.jmp´´) is attached.

Questions:

  1. How to obtain the statistics for each distribution (bottom and top position)?
  2. How to deduce the statistics for height of each sample (1 to 5)?
  3. How to obtain the t-test and equivalent test to compare the deduced 5 heights?

Many  thanks for your help!
