personal finance home financing# How do you find the missing value when given the median?

**median**is the average of the two middle numbers, andtheonly way to find the

**missing**number is if the

**median**is one of those two numbers. If it is, you can takethe

**median**and the one of the two numbers you know. Usetheformula (# +#)/2=

**median**and solve.

In this manner, how do you find the missing number?

You can find the mean by adding the set of**numbers**and dividing by how many **numbers** are given.If you are giventhe mean and asked to find a **missing number**from the set, usea simple equation.

**median**is also the number that is halfwayintothe

**set**. To

**find the median**, the

**data**should bearranged in order from least to greatest. If there is aneven numberof items in the

**data set**, then the

**median**is found bytaking the mean (average) of the twomiddlemostnumbers.

Just so, how do you get the median if there are two numbers?

**If there** is an even **number**of**numbers** locate the **two** middle **numbers** sothat**there** is an equal **number** of **values** to theleftand to the right of these **two numbers**. Step 3:**Ifthere** is an odd **number** of **numbers**, thismiddle**number** is the **median**. **If there** is aneven**number** of **numbers** add the **two** middlesanddivide by 2.

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.
