Chi-square Tests

In this module, we are going to discuss and explore a statistical test used for “goodness of fit”. What does this mean? You know whether your shoes fit your feet based on whether they cause pain, right?

In sort of the same way, you can decide whether your data fits your expectations using a “goodness of fit” test. And believe me, if your data doesn't fit, it can cause a lot of pain…

 

Note: having a calculator on hand will make things go faster. You can also use a spreadsheet, or calculator software on your computer, or google (to use google, type the numbers into the search bar, followed by an equal sign, and hit search).
