PLEASE COMMENT below the MCQ with the CORRECT ANSWER and its DETAILED EXPLANATION.

Don’t forget to mention the MCQs Statement (or Screenshot), because MCQs and their answers are generated randomly

The field of statistics deals with the measures of central tendency (such as mean, median, mode, weighted mean, geometric mean, and Harmonic mean) and measures of dispersions (such as range, standard deviation, and variances).

The Basic 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 statistical analysis to draw meaningful inferences.

A basic visual inspection of data using some graphical and numerical statistics may give some useful hidden information 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.
