Statistical Too...

When the values in a series do not have equal importance, we calculate the:

To calculate the median, all the items of a series have to be arranged in a/an:

What is the mean of the range, mode and median of the data given below?

\(5,10,3,6,4,8,9,3,15,2,9,4,19,11,4\)

What is the mode of the following numbers?

\(10,21,10,12,21,10,21,21,21,12,13,21,12\)

Following is arranged in ascending order. If the median of the data is 63, find the value of \({x}\) in a series \(29,32,48,50, x, x+2 ,72,78,84,95\).

For a symmetrical distribution, which is correct:

Percentiles divide the series into:

If the mean of five observations \(x, x + 2, x + 4, x + 6, x + 8\) is \(11\). Find the mean of 1st three observations.

The numbers \(5,7,8,10,12,13\) and \(N\) are arranged in ascending order. If the mean of the numbers is equal to the median, the value of \(\mathrm{N}\) is :

In a symmetrical distribution, the number of observations smaller than ________ is the same as the number of observations larger than it.
