Similarly, how do you find the missing number when given the median?
If there is an even number of numbersinthe set, the median is the average of the twomiddlenumbers, and the only way to find the missingnumberis if the median is one of those twonumbers. If itis, you can take the median and the oneof the twonumbers you know. Use the formula (#+#)/2=median andsolve.
Also Know, how do u find the mean? Mean is just another name for average.Tofind the mean of a data set, add all thevaluestogether and divide by the number of values in the set. Theresultis your mean! To see an example of finding themean,watch this tutorial!
Moreover, how do you find the mean when given the frequency?
The Mean from a Frequency Table. It iseasyto calculate the Mean: Add up all the numbers,thendivide by how many numbers there are.
What is the formula of median?
The mean (average) is found by adding all of thenumberstogether and dividing by the number of items in the set: 10+ 10 +20 + 40 + 70 / 5 = 30. The median is found by orderingtheset from lowest to highest and finding the exact middle.Themedian is just the middle number: 20.
