Sum of u statistics
WebDefinition 3.2. The statistic Un in (1) is called a U-statistic with kernel h of order m. The use of U-statistics is an effective way of obtaining unbiased estimators. In nonparametric problems, U-statistics are often UMVUE’s, whereas in parametric prob-lems, U-statistics can be used as initial estimators to derive more efficient estimators. WebAlso, the data will be in the form of a frequency distribution table with classes. Thus, the formula to find the mean in assumed mean method is: M e a n, ( x ―) = a + ∑ f d i ∑ f. …

When there is an odd number of rows, the median will be the middle value of the original data after it is ranked. If there is an even number of rows, you take the average of the two values in the middle. Here the median is 21.
