Introductory statistics deals with the measure of central tendencies (that include mean (arithmetic mean, or known as average), median, mode, weighted mean, geometric mean, and Harmonic mean) and measure of dispersion (such as range, standard deviation, and variance).

Introductory statistical methods include planning and designing the study, collecting data, arranging, and numerical and graphically summarizing the collected data. Basic statistics are also used to perform different statistical analyses to draw meaningful inferences.

A basic visual inspection of data using some graphical and also with numerical statistics may give useful hidden information that is already available in the data. The graphical representation includes a bar chart, pie chart, dot chart, box plot, etc.

Companies related to finance, communication, manufacturing, charity organizations, government institutes, simple to large businesses, etc. are all examples that have a massive interest in collecting data and measuring different sorts of statistical findings. This helps them to learn from the past, noticing the trends, and planning for the future.

Various graphical and numerical ways are used to check the skewness of the data. Skewness is the lack of symmetry in distribution.
