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 also used to perform different statistical analyses to draw meaningful inferences.

Basic Statistics MCQs Test

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