My Take On Hypothesis Testing

MY TAKE ON HYPOTHESIS TESTING Hypothesis testing is also called significance testing or "null hypothesis significance testing." The hypothesis testing unit is the most important unit of our course. We have one hypothesis test concerning one unknown population mean. Separately from that, we have one hypothesis test concerning one unknown population proportion. As you go on to take future courses in quantitative research and statistics, you go on to learn about many more other types of hypothesis tests / hypothesis testing. Thanks Friends and please see the slides below for some fundamental introductory material about hypothesis testing / significance testing. Be well and Best Wishes Friends !! :) MY TAKE ON the THREE TYPES of HYPOTHESIS TESTS Hi Friends ! There are 3 major types of hypothesis tests that we study and learn about in the course. One type is called a right tailed test ( also called an upper tailed test ) Another type is called a left tailed test ( also called a lower tailed test ) A third type is called a two tailed test. These give rise to ( on our Week 7 Excel spread sheet calculator ) one sided P-Values and respectively two sides P-Values. So to be more clear about it, one sided P-Values are associated with both left tailed tests and right tailed tests. On the other hand, two sided P-Values are associated with two tailed tests only. Thanks Friends and please see the slides below for some important background and information concerning Types of Hypothesis Tests. Good Luck and Best Wishes Friends !! ;) MY TAKE ON the STEPS for HYPOTHESIS TESTING Hypothesis Test problems and exercises probably have more steps for lack of a better way of putting it than perhaps anything else that we study or learn about in the course. So the slides here are offered to you in order to hopefully help you keep all those steps straight and organized and so forth. What will probably be more confusing to many of you is that many of the Knewton problems and exercises in the Week 7 homework only focus on doing certain parts or steps of the process and not always "the whole process from beginning to end." Does that make any sense ? If it does not make total sense now, what I meant here will be clear to you by the time you finish all of your Week 7 Knewton Homework. Thanks Friends and these slides here are a great guide / template / road map as you try to make sense out of what we are trying to teach you during Week 7 of the course. Thanks again Friends and take good care and Best Wishes too !! :)
