List of top Quantitative Aptitude Questions on Mean, median, mode and standard deviation

The Standard Deviation of 2, 4, 6, 8, 10 is

In a moderately asymmetrical distribution, the mode and mean are 32.1 and 35.4 respectively. Calculate the median.

Find the median of the following observations: 6, 49, 14, 46, 16, 42, 26, 32, 28

The mean, median, mode and range of the observations \(7, 6, 7, 9, 14, 9, 7, 15\) is:

Match List - I with List - II.

List - I		List - II
(A)	Mean	(I)	Average of given values
(B)	Median	(II)	Mid value when data are sorted in  ascending/descending order
(C)	Mode	(III)	Data value that appears most number of times
(D)	Range	(IV)	It is the difference between the  maximum and minimum values

Choose the correct answer from the options given below :

Standard deviation is:

Match List I with List II

List I- (Statistical term)		List II-(Description)
A	Statistics	I	Numbers which occur frequently in population
B	Mode	II	Arithmetic average
