Independent Sample Student's Test

Independent Sample Student's't Test is used to compare two small sets of quantitative data when samples are collected independently of one another. Student's t test for independent samples is used to determine whether two samples were drawn from populations with different means. When one randomly takes replicate measurements from a population he/she is collecting an independent ...

#### Solution Summary

The solution gives the situations in which paired t test and independent sample t test are appropriate.
