Biostatistics Exam Problems
Hi,I need help on this Friday's statistics exam. This course used SPSS software, which means you need to understand the graphs and forms from SPSS. This course mainly about statistics, such as Chi-Square test (Goodness-of-fit test, r*c contingency table, Mantel-Haenszel test), ANOVA (one-way, Kruskal-Wallis test; RBD two-way, Friedman-Kendall-Smith test), Correlation Analysis, Linear Regression, Logistic Regression, Survival Analysis, Proportional Hazards. You also need to be familiar with the basic knowledge of statistics, such as p-value, t-test, z-test, paired samples, Independent samples(common variance&unequal variances), Sample size estimation, Wilcoxon signed rank test, Wilcoxon rank sum test, population proportion, odds ratio. And also a chapter of Prevalence. I upload the example test with answer, but due to switch to the online test, the questions should be all multiple choice questions.Please check. Thanks for your help ! !
