Question

What is the median of 90,30,20,30,60,30,80

Answer 1

The median is 30.

Explanation:

To find the median, you must first list all numbers from least to greatest.

In this case, we get 20, 30, 30, 30, 60, 80, 90.

Median is the middle number in the group. Here, we can clearly see that 30 is the middle number.

Keep in mind that if a group doesn't have a middle number, a.k.a. even number of numbers, take the 2 middle numbers, add them, then divide the sum by 2 to get the median.

Answer 2

you have an odd number, divide by 2 and round up to get the position of the median number.

Explanation:

you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
