Non parametric statistics

1. Give a scenario that would require you to use a non-parametric statistic, such as ranking.
When comparing the means of two populations, one option is to use an independent samples t-test (Sometimes called "Student's t test". See the response to question 2). In order for a Student's t test to be valid, we must assume:

1. Samples were randomly and independently selected from two populations.
2. The populations from which the samples were selected have normal distributions.
3. The populations from which the samples were selected have the same ...
