Mode of set of 20 observations is 18 and skewness of observations around central value is 5 then calculated value of arithmetic mean of observations is
Sum of squared deviation of sample mean is 48 and total number of observation is 13 then population variance is
Number of patients who visited cardiologists are as 63, 57, 51, 65 in four days then absolute mean deviation (approximately) is
In statistical procedures, skewness is used to measure the
First quartile of data set is 12, third quartile of data set is 18 and median is 9 then absolute skewness of same data set is
If value of first quartile is 49 and value of third quartile is 60 then value of inter quartile range is
Coefficient of skewness method in which basis of measuring is deciles and percentiles is classified as
Characterization, collection and presentation of particular set of data in organized way is classified as
