Business Statistics MCQs: 220 Questions & Answers in Faculty

The first three moments of a distribution about the mean are 1, 4 and 0. The distribution is:

In a symmetrical distribution, Q3 – Q1 = 20, median = 15. Q3 is equal to:

In a mesokurtic or normal distribution, µ4 = 243. The standard deviation is:

The degree of peaked ness or flatness of a unimodel distribution is called:

If the sum of deviations from median is not zero, then a distribution will be:

For a positively skewed distribution, mean is always:

If mean absolute deviation of set of observations is 8.5 then value of quartile deviation is

If the arithmetic mean is multiplied to coefficient of variation then the resulting value is classified as

For the recorded observation, the ratios measured by absolute variation are considered as

The sum of all the squared deviations is divided by the total number of observations to calculate

A distribution consists of three components with total frequencies of 200, 250 and 300 having means 25, 10 and 15 respectively. Find the mean of the combined distribution.
