Answer:
The median is 69.5
Step-by-step explanation:
The median is also known as the middle value. To find the median, you first arrange your data in numerical order.
Numerical order:
50, 50, 53, 55, 55, 57, 62, 63, 64, 64, 65, 68, 68, 69, 69, 70, 71, 71, 71, 72, 72, 73, 75, 75, 75, 77, 77, 78, 79, 80
There are 30 numbers, which means that the median is between the 15th and 16th value (69 and 70).
69 + 70 = 139
139/2 = 69.5
Therefore, the median of this data set is 69.5
Hope this helps!
