science physics# How do you find the missing number when given the mean?

Last Updated: 25th June, 2020

**mean**of a set of

**numbers**isthe

**average**of those

**numbers**. You can findthe

**mean**by adding the set of

**numbers**and dividing byhowmany

**numbers**are

**given**. If you are

**giventhemean**and asked to find a

**missing number**from theset,use a simple equation.

Similarly, how do you find the missing number when given the median?

If there is an even **number** of **numbers**inthe set, the **median** is the average of the twomiddle**numbers**, and the only way to find the **missingnumber**is if the **median** is one of those two**numbers**. If itis, you can take the **median** and the oneof the two**numbers** you know. Use the formula (#+#)/2=**median** andsolve.

Also Know, how do u find the mean? **Mean** is just another name for **average**.To**find** 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 the**mean**,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.The**median** is just the middle number: 20.
