Mean Median Mode
Practice Mean Median Mode MCQs from Statistics — Mathematics.
A student scored 70, 80, and 90 in three tests. What score does he need in the fourth test to have a mean of 85?
In a distribution, if Mean < Median < Mode, the distribution is:
If the mean of 10 observations is 20 and another 10 observations is 30, the combined mean is:
Find the mode of 1, 2, 2, 3, 3, 3, 4, 4, 4, 4.
If the mean of x-5, x-3, x, x+3, x+5 is 15, find x.
If the sum of squares of deviations of 10 observations from their mean is 0, then:
If the mean of $x_1, x_2, ... x_n$ is $\bar{x}$, what is the mean of $ax_1+b, ax_2+b, ... ax_n+b$?
In a grouped frequency distribution, if the median class is 20-30, L=20, N=40, cf=15, f=10, h=10, the median is:
The mean of 100 observations was calculated as 40. Later it was found that an observation 53 was misread as 83. The corrected mean is:
If for a given data, $\sum (x-5) = 10$ and $n=20$, then the mean is:
For a data set with 50 items, the mean is 100. If each of the first 25 items is increased by 2, and each of the last 25 items is decreased by 2, the new mean is:
If the mean of $n$ numbers is $M$, and the sum of first $(n-1)$ numbers is $S$, the $n^{th}$ number is:
Calculate the mode for the following data: 2, 3, 3, 5, 5, 5, 7, 7, 8, 8, 8. What can be said?
The combined mean of two groups of 40 and 60 observations are 25 and 30 respectively. The combined mean is:
If the mean of first $n$ natural numbers is $3n/5$, then $n$ is:
In a continuous series, the median is 35 and the median class is 30-40. If f=10 and h=10, and N=50, what is the 'cf' of the pre-median class?
If the ratio of mode and median of a distribution is 6:5, then the ratio of mean and median is:
The mean of 20 observations is 15. On checking, it was found that two observations 20 and 15 were miscopied as 3 and 32. The correct mean is:
