What conditions are necessary in order to use a t​-test to test the differences between two population​ means?.
Sliva [168]

The two samples must be independent and each must be drawn at random from any population. The two samples must be independent and each must be drawn at random from a healthy population.

<u>What is nominal scale?</u>

A nominal scale is a measurement scale that is used to categorize events or things into distinct groups. This type of scale only needs one-of-a-kind identifiers to mark each separate category instead of requiring the usage of numerical values or categories ranked by class.
