The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.

The median uses the position of the data rather than their actual values. As a result, in general, you will only be able to determine whether the missing value is greater than or less than the median.

Simple answer:Divide the total number of observations (plus 1, if small) by 2 to find the middle rank.Look at the cumulative frequencies for the grouped data and find the group in which the middle rank would appear. That is the median group.More sophisticated answer:Withing the median group, interpolate.

The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (10, 17, 20, 45, 68) The median is 20.

A quartile is a given section in a range of data. To find the quartile, you must first find the median. Then find the "median of the median", using these to separate your data into sections, giving you a total of four sections of data.
