- What are the two types of statistics? (5pts.)

The two types of statistics are descriptive and inferential. In descriptive statistics, the data of a population is summarized graphically or numerically through derivation of statistics related to central tendency and dispersion around the same. The shape and nature of distribution is also used in descriptive statistics. In inferential statistics, the parameters of a population are inferred according to sample statistics. This involves the estimation of statistics of a group allowing for approximation of information data relating to the entire population. In this type of statistics, modeling are used to generate mathematical ...

Types and level of statistics

There are two types of statistics, namely: descriptive and inferential statistics. Descriptive statistics quantitatively describes features of a set of data represented numerically. It involves summary of the population data numerically or pictorially/graphically thereby deriving measures of central tendency, measures of dispersion, relationship and correlation and measures of Skewness and kurtosis (Witte & Witte, 2010). Inferential statistics entails studying a statistical ...

The first part of typical statistical research is descriptive statistics of the data sample.

Descriptive statistics allows to generalize the initial results obtained by observation or experiment. All calculations descriptive statistics are reduced to group data according to their values ​​, their frequency distribution of construction , identify trends central distribution and finally to the estimation variance of the data with respect to the central tendency found . Presentation of descriptive statistics is usually the first step in any analysis .
