Mean and variance of an ungrouped data of 15 numbers are \(12\) and \(14\) respectively. For another ungrouped data of 15 numbers the mean and variance are \(14\) and \(10\) respectively. If the two data are combined, then the variance of the combined data of 30 numbers is

The mean deviation from the median of the given frequency distribution is:

Mean deviation from the mean for the ungrouped data \[ 8,\,7,\,15,\,12,\,12,\,60,\,15,\,6,\,65,\,4,\,6,\,18 \] is

The mean deviation about median of the numbers $3x, 6x, 9x, ..., 81x$ is 91, then $|x|=$

The mean deviation from the mean of the discrete data 2, 3, 5, 7, 11, 13, 17, 19, 22 is

The variance of the discrete data 3, 4, 5, 6, 7, 8, 10, 13 is
