Complex statistics enable us to draw inferences and make predictions from the sample data about the population. This includes: comparative analysis, correlation analysis, regression analysis (odds ratio), survival analysis (Cox regression & Kaplan Meier curve, Hazard ratio), reliability analysis, factor analysis, ROC curve analysis (sensitivity, specificity, accuracy, optimal cut off), and other statistical tests (including Chi square test, t – test , one way ANOVA, Post Hoc test , Non Parametric test, etc.).
Simple statistics provide descriptive information regarding the variables in the data set. It includes: Measures of Frequency (Count, Percent, Frequency), Measures of Central Tendency (Mean, Median, and Mode), Measures of Dispersion or Variation (Range, Variance, Standard Deviation), and Measures of Position (Percentile Ranks, Quartile Ranks).
