Description: What is holding you back from doing clinical research? Don't wait to make your life better!I've been a statistician for 25 years and I know what statistics you need to know. I see more and more evidence that researchers are going to need to have technical skills. I gave you a lot of introductory information in this course to give you a strong foundation.  I will give you the secret very few scientists know. These are some of them.If you are doing a Retrospective Study you can't get incidence. You can get the Odds Ratios and the hospitalized prevalence. If you want to do a case control study you will be sampling cases and controls so what you will be testing is the rate of exposure in the treatment vs the rate of exposure in the control.If you are doing a single time point survey you are doing a Cross-sectional Study. In the cross-sectional study you can determine the relationships you're interested in that are existing now in the data. You can ask about something that happened in the past but it is not a pre/post study design, because you only have observational data in the past. In these studies you can do t-tests and odds ratios.If you are doing a pre/post study design you are doing a Longitudinal Study. In these studies you can do a proper pre/post analysis and since your study has a baseline you can do an intervention study. It can be as simple as a paired t-test or as difficult as a multivariable linear regression. A Survival study is a special form of a longitudinal study and it can be analyzed with specialized methods like Kaplan Meier, the Log-rank test, or an advanced Cox multivariable regression.Have you ever felt lost knowing where to start a research study, unsure how to translate raw secondary data from a retrospective study into meaningful insights that can truly impact lives?  Do you want to have
