Answer:

50

Step-by-step explanation:

The mean of a data set refers to the average. To find the average, calculate the sum of the data and divide by the number of values.

[tex]\frac{20+50+80+50}{4}=\frac{200}{4}=50[/tex]

Add all four numbers up you get 200. Since you have 4 numbers in the data set you divide 200 by 4 which is 50
The answer is 50
