![]() But later segments of homework will have lengthy questions (like finding linear regression equations). At first, the homework might seem easy (especially when dealing with means or bar graphs). It sounds obvious, but when I was teaching stats, the students who got the lowest grades tended to be the ones who started the homework on Sunday night (the homework was due Monday). See how that works? Statistics Made Easy Tip #6ĭon’t leave your homework until the night before. In order to run a hypothesis test you need to know how to state the null hypothesis. In order to find a P Value you need to run a hypothesis test to get a test statistic (like an F Statistic). Elementary statistics builds on information in the same way that a recipe does: if you don’t know what “crack an egg” means, then you won’t be able to fry it. Statistics Made Easy Tip #5ĭon’t skip over a definition if you don’t understand it. That means you can change your inputs after you’ve made your graph, allowing you to see how different factors (like changing bin size) affect your graphs. ![]() But the nice thing about Excel is that it’s dynamic. Why? Some graphs (like the graphs produced by simple linear regression) can be tricky to wrap your head around. ![]() But the most important part of the class is the test (especially true with AP Stats!) and a graphing calculator will be invaluable. Your instructor might insist that you learn how to do things by hand for homework. Use a TI-83 or a TI-89 calculator, starting at the beginning of your class.
