Statistical Function
The function of statistics is
- Descriptive function: Namely the statistical function in understanding, describing, explaining data, events, which are collected in a research, investigation and do not arrive at generalizations or conclusions about populations that are investigated

Types of Statistics
The following are the types or types of statistics
Based on the Discussion Orientation
- Mathematical statistics: The same as theoretical statistics, which emphasizes understanding of models, derivation of concepts and formulas statistical-mathematical-theoretical, such as understanding and using t-test, normality test, regression analysis, homogeneity test, error and etc
- Applied statistics will prioritize the understanding of statistical concepts and techniques as well as their use in certain scientific disciplines
Based on the Phase or Purpose of Analysis
- Descriptive statistics: Relating to the collection, processing, analysis, presentation of data without general conclusions or generalizations. Data is presented in the form of tables, charts, graphs, circles, polygons, calculations of mean, median, mode, percentile, decile.
- Inferential statistics that allow general conclusions to be drawn
Based on the Assumed Distribution of the Data Population Analyzed
- Parametric statistics: namely statistics based on the normal distribution model.
- Non-parametric statistics: namely statistics with techniques that are not based on the normal distribution model or the free distribution
Based on the Number of Dependent Variables
- Univariate Statistics: Statistics that have only one dependent variable
- Multivariate Statistics: Statistics that have more than one dependent variable
