Answer:

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.
