This quiz contains MCQs Basic Statistics first year with answers covering variable and type of variable, Measure 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 Basic Statistics first year 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.

Great content Sir,,,How did you arrive at the answer for this question? 15. For a certain distribution if $\sum(x-2)=18, \sum(x-24)=0, \sum(x-28)=-24$ then arithmetic mean is

Thank you for visiting and liking my site.

The answer is by using the arithmetic mean property that the sum of deviations from mean is always zero $(\sum(X-\mu)=0$.

that’s Great Job,!

very good mcq sir
