What is holding you back from doing clinical research? 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 that, aha! moment, when your research is a success? If you answered yes to any of these questions, then you're in the right place. Prepare to embark on a journey that will transform you from a passive observer of data to an active interpreter, an expert of the powerful tools of biostatistics. I made this course using 23 years of experience and over 30 articles in peer reviewed journals as the analyst, to give you exactly what you need to analyze data the right way, and make sense of it. I feel knowing biostatistics will make you indispensable. I believe every student should know this information.Imagine being able to confidently analyze clinical trial results, evaluate the effectiveness of new treatments, and even predict the spread of diseases. Think about the impact you could have by contributing to groundbreaking research, shaping public health policy, and ultimately, improving human health. Biostatistics is the key that unlocks these possibilities. It's the bridge between raw biological data and actionable knowledge. This isn't just about crunching numbers; it's about uncovering the truth hidden within the data, revealing the patterns that would otherwise remain unseen. The easy medical problems have been solved, your going to need the best tools to solve the problems we are seeing today.By the end of this course, you won't just understand biostatistics; you'll be able to apply it. You'll gain the confidence to critically evaluate research findings, design your own studies, and contribute meaningfully to the scientific community. This course will empower you to: * Read and interpret scientific literature with confidence: You will learn what is the method to analyze observation studies, cross sectional studies, or use secondary data for your research. No more being intimidated by statistical jargon or complex graphs. You'll be able to dissect research papers and understand the implications of the findings. * Conduct your own statistical analyses: You'll learn how to use statistical software (like R or SPSS) to analyze data and draw your own conclusions. * Communicate statistical findings effectively: You'll develop the skills to present complex data in a clear and concise manner, whether you're writing a research paper or giving a presentation. * Become a valuable asset in any research team: Biostatisticians are in high demand across a wide range of industries. This course will give you the skills and knowledge to stand out from the crowd.Elevate your career in any field today. You can Also Use this class to start the statistics portion of a Data Scientists career. Do more research better.Prerequisites: You will need basic mathematics knowledge to work with formulas discussed in this course. You could take an Introduction to Statistics course first.Earn a CertificateWhen you finish listening to all videos, assignments, quizzes and practice exams, you'll earn a Certificate that you can share with prospective employers and your professional network.Who this course is for:Anyone wanting to get into the Public Health/ Pharmaceutical / Medical Research industry and work in this fieldWant to take up a job as a Clinical Data Analyst in a Pharma company or a Research Hospital. Want to just feel comfortable with basic statistics used the same fieldsReady to unlock the power of biostatistics? Enroll in this course today and take the first step towards becoming a data detective. Don't just observe the world; understand it. The future of health and well-being depends on our ability to interpret the stories hidden within data. This course will give you the tools and the knowledge to become a part of that vital work. Enroll now to begin your journey to end the boring job life. We look forward to welcoming you to the exciting world of biostatistics! Thank you for considering this course.
