Mean Median Mode
Practice Mean Median Mode MCQs from Statistics — Mathematics.
Mean of 100 observations is 50. If one observation 50 is replaced by 150, the new mean is:
Find the mean of prime numbers between 10 and 20.
The relationship Mode = 3 Median - 2 Mean holds for:
If the mean of a distribution is 25 and the coefficient of variation is 20%, the standard deviation is:
The median of the data 13, 15, 16, 17, 19, 20 is:
Find the mean of first five odd prime numbers.
If $x_1, x_2...x_n$ are observations such that $\sum (x_i - 2) = 20$ and $\sum (x_i - 5) = -10$, then $n$ is:
Which measure is best for 'salary' distributions which are often skewed?
Mean of $n$ observations is $\bar{x}$. If each is divided by 10, the new mean is:
If the mean of 6, 8, 5, 7, x and 4 is 7, then x is:
In a symmetric distribution, Mean - Median = ?
Calculate the median for: 40, 50, 30, 60, 80, 70.
If for a series, $\sum fx = 200$ and mean = 20, then $\sum f = $ ?
