The mode of a set of observations is the value which

The mean of first six multiples of 4 is

The frequency polygon is drawn :

What is the mode?

The mean of first five prime numbers is

The mean of x-5y, x-3y,x-y, x+ y, x + 3y and x+ 5y is 12. Then the value of x is

The A.M of d -2, d, d, d+2 is

Formula for the median of grouped data is

The mean and median for a unimodel data are 43, 43.4 respectively. Find the mode.

The mean of , ,,and is

The sum of 15 numbers is 420. The mean of those numbers is

The sum of all the deviations of the observations of a data from its A.M. is

In a frequency distribution, C= 3, l = 66.5, t =42, m = 23 n = 102. Find the median of the distribution.

The mean of a data is 'P'. If each observation is multiplied by 3 and then 1 is added to each result, the mean of the new observations so obtained is

The mean of 20 observations is p. If each observation is multiplied by 3 and then 1 is added to it, the new mean obtained will be

The median of 10, 20, 15, 30, 35, and 42 is

The median and A.M of a unimodel data are 30.5 and 26.2 respectively. Find its mode.

The mean of 11 observations is 17.5. If an observation '15' is deleted, the mean of the remaining observations will be

The arithmetic mean of a - 2, a and a + 2 is

One of the properties of mode is
