If $N=100$ and median position is given by $N/2$, what is the position?

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

If mean is 15, median is 16, then the distribution is:

The mean of 5 observations is 7. If a new observation 13 is added, the new mean is:

The median of first 9 natural numbers is:

If each observation is decreased by 10%, the mean:

In the formula for mode $L + \frac{f_1 - f_0}{2f_1 - f_0 - f_2} \times h$, $f_1$ is the frequency of:

If the mean of two numbers is 5 and their product is 24, the numbers are:

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:
