Two Sample T Test
Definition
A two sample t-test is used to compare means from two independent groups or samples. It helps determine if there is enough evidence to conclude that there is a significant difference between their means.
Analogy
Imagine you want to compare the average height of male students and female students at your school. You randomly select samples from each group and calculate their mean heights. By performing a two sample t-test, you can determine if there is sufficient evidence to suggest that there is indeed a significant difference in average height between male and female students.
