Statistical Methods - Biostatistics

Dive into a comprehensive 7-hour tutorial on biostatistics and statistical methods, covering essential topics such as hypothesis testing, z-tests, chi-square tests, Student's t-tests, and Fisher's F tests. Learn about samples and populations in statistics, one-tailed and two-tailed tests, significance levels, and the procedure for hypothesis testing. Explore critical z-values, null and alternative hypotheses, and gain practical experience through numerous questions and solutions. Delve into the fundamentals of t-distributions, paired and unpaired t-tests, goodness of fit tests, and the properties of F distributions. Conclude with an in-depth look at Analysis of Variance (ANOVA), including both one-way and two-way ANOVA techniques, accompanied by step-by-step explanations and numerical problems to reinforce your understanding of these crucial biostatistical concepts.
