This quiz contains MCQs Introductory Statistics with answers covering variable and type of variable, Measures of central tendency such as mean, median, mode, Weighted mean, data and type of data, sources of data, Measures of Dispersion/ Variation, Standard Deviation, Variance, Range, etc. Let us start the MCQs Introductory Statistics with answers Quiz.

Basic statistics deals with the measure of central tendencies (such as mean, median, mode, weighted mean, geometric mean, and Harmonic mean) and measure of dispersion (such as range, standard deviation, and variances).
Basic 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 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.

If any the value in data set is zero then it is not possible (i.e. impossible) to compute

Harmonic mean.

It’s very helpful for CA student’s….send me some more test and results based on regression
