Here’s a quick example:

Let’s say you’re an educator and you want to know who performs better in graduate school tests – students who came to grad school straight from college or those who worked first?

You go to a graduate school and ask for the test scores from each class. Here’s what you get from the school:

Students with work experience | Students without work experience | |||

Class | Average Score | # of students in class | Average Score | # of students in class |

A | 83 | 15 | 80 | 5 |

B | 70 | 5 | 79 | 15 |

C | 92 | 10 | 86 | 10 |
