Find the mean of 1, 2, 2, 3, 3, 3.

The median of 4, 1, 3, 2, 5 is:

If the mean of 10 observations is 25 and each is multiplied by 2 and then 5 is subtracted, the new mean is:

If the sum of 50 observations is 2500, what is the mean?

Median can be found graphically using:

Mode of the data 7, 8, 9, 10, 7, 8, 7 is:

The mean of the first $n$ natural numbers is:

If mean = 10 and median = 12, then mode is:

A data has mean 20. If 5 is added to each term, the coefficient of variation will:

Median of 2, 8, 3, 7, 4, 6, 5 is:

If the mean of 5 observations is 10, the sum of deviations from 10 is:

Find the mode of class 0-10 (f=5), 10-20 (f=10), 20-30 (f=5).

If the mean of 4, 7, 8, 6, x is 7, then x is:

The mean of the first 50 even numbers is:

What is the mode of 1, 1, 2, 2, 3, 3?

The median of 10, 12, 14, 16 is:

If for a distribution, mean = 25 and mode = 25, then the median is:

What is the arithmetic mean of the first five prime numbers?

In a data set, if the median is 15 and the mean is 15, what is the most likely value for the mode if the distribution is perfectly symmetrical?

If the mean of five observations x, x+2, x+4, x+6, and x+8 is 11, find the value of x.
