How do you find 3 missing frequencies when median and mode given?

How to find the missing number if median is given?
Well, isn't that just a happy little problem to solve! To find the missing number when the median is given, you'll want to first list all the numbers in order. Then, if the median is the middle number, you can easily identify the missing number based on whether it falls before or after the median. Just remember, there are no mistakes in math, only happy little accidents!
How do you find the missing number in a data set if there is no mean?
If there is no mean it is very rare that you will be able to find a missing number. Potentially if you have other numbers and you have a mode you can deduce the missing number by using the mode (if there needs to be one more of a certain number or a certain number cannot be increased in its count of numbers i.e. you can't have more 6's to maintain the current mode).
How do you find th number missing if the median is 104?
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.
Median formula for grouped data?
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.
