T Test. The t test tells you how significant the differences between groups are. Student s test t test notes when the difference between two population averages is being investigated a t test is used.
A t test is a statistical test that is used to compare the means of two groups. You can compare a sample mean to a hypothesized or target value using a one sample t test. A t test is the most commonly applied when the test statistic would follow a normal distribution if the value of a scaling term in the test statistic were known.
It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest or whether two groups are different from one another.
