You find the median to find the middle number
The middle number (in a sorted list of numbers).To find the Median, place the numbers you are given in value order and find the middle number.Example: find the Median of {13, 23, 11, 16, 15, 10, 26}.Put them in order: {10, 11, 13, 15, 16, 23, 26}The middle number is 15, so the median is 15.(If there are two middle numbers, you average them.
The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
you find the two numbers in the middle and add them. divide the sum by two. that's the median.
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!

Given the median and trapezoid MOPN, what is the value of x?
0-10 4 10-20 6 20-30 x 30-40 y 40-50 Z 50-60 6 60-70 4 total 200 median=33.5 mode=34
The answer depends on what information you do have.
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).
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.

it is used to find mean<median and mode of grouped data
find the frequency before finding the percent total -_- :)

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.
