Statistics is one of the involved subjects in the academics. Statistics is the science and practice of developing human knowledge, it is the branch of mathematics dealing with the study of collection, analysis, interpretation, presentation, and organization of data in particular fashion, presentation of data by use of the graph, figures. The whole data is collected, and comparatively, the study is made. A statistical model is also known as the statistical population it is used for surveying a country, city population.
There are two types of statistics descriptive and inferential statistics. The descriptive statistics tries to summarize a set of data. Under this category we have measures of central tendency and measures of dispersion as the key types of descriptive statistics. The median, mode, and mean are the three types of measures of central tendency. On the other hand, the variance, range and standard deviation are the tests of dispersion. The primary aim being summarizing data from any given sample of data to take our mean, deviation it helps to take out conclusions from data by checking the examples and observation errors in the experiment, or in the sample. Looking at the measures of Central Tendency, the mean applies a single value to give a description of the center of data set. The mode, median and mean are three types of Measures of Central Tendency.
The second type of statistic is Inferential statistics which allows you to take data and use it to conclude the population by sample analysis and observation. Inferential figures do compare, test and predict data. The result we get in probability, and it uses to explain chances of occurrences of events. The function of Inferential statistics is to reach the calculation to learn about population, which extends beyond the data available.
