t-Test

T-tests are a type of statistical test that is used to compare the means of two groups. They are often used in hypothesis testing to determine if there is a significant difference between the means of two groups. T-tests can be used to compare means of two independent groups or two dependent groups.

What is a T-Test?

A t-test is a statistical test that determines whether there is a significant difference between the means of two groups. A t-test is used when the sample size is small, the population standard deviation is unknown, and the data is normally distributed. To perform a t-test, the mean and standard deviation of each group must first be calculated. The t-statistic is then calculated by dividing the difference between the means of the two groups by the standard error of the difference. The t-statistic is then used to determine the p-value. The p-value is the probability of obtaining a t-statistic as large as the one that was calculated, assuming that there is no real difference between the means of the two groups.

Why Learn About T-Tests?
