Hi, can anyone tell me if I can use the paired sample t-test to analyze the Likert scale data? I used the retrospective survey to obtain the data (pre and post) on respondents in various statements.Thanks!

The validity of the test depends on the normal distribution of the test data only. Any numerical data showing the normal distribution is suitable for the t-test. When the data deviate greatly from the normal distribution, the sign test is be useful. Nevertheless, normal distribution usually happens to any rating scale.

As is common knowledge, a CSSA applicant must pass both the asset and income tests. Can the two tests be seen as resources or activities when using the logical model?

Integrated Employment Assistance Programme for Self-reliance (IEAPS) statistics are being read by me. And I discovered that between April 1, 2017, and March 31, 2020, 25% of service receivers had found job or had gone back to regular education for at least one month. Then, may I declare that it is a software output?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
