How do you find missed frequency if median and mode are given

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.
Given the median and trapezoid MOPN, what is the value of x?
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.
To find the median temperature over a given period of time, arrange the recorded temperatures in numerical order and take the value in the centre.
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.
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.
You find the median to find the middle number
