Unit 1

Need of biostatistics Descriptive statistics: Population and samples descriptive methods for categorical data descriptive methods for continuous data probability and probability distributions types of data frequency distribution measures of central tendency measures of variability kurtosis and skewness Z score

Unit 2

Inferential statistics Parameters estimating and comparing the mean of population. Hypothesis testing: basic concepts and steps testing normal distribution – Kolmogorov-Simon test testing homogeneity of variance – Levine’s test Z-tests dependent t-test, independent t-test, t-test as GLM, F-test, Chi-square test Type I and type II errors ANOVA, ANCOVA, factorial ANOVA, repeated-measures designs, mixed design ANOVA, post hoc procedures.

Unit 3

Non-parametric tests non-parametric and distribution-free tests – Mann-Whitney test Wilcoxon signed-rank test, Wilcoxon signed rank sum test, Kruskal-Wallis test, Friedman’s ANOVA.

Unit 4

Correlation techniques Bivariate correlation – Pearson’s correlation coefficient, Spearman’s correlation coefficient Partial correlation regression – method of least squares, assessing goodness of fit multiple regression. Experimental design and clinical trials.
