The median will be 66.

Step-by-step explanation:

The median is defined as the middle value which separates the higher half from the lower half of any given data sample.

The given set here is : 66, 51, 77, 68, 60, 75, 54, 80, 29, 64, 66, 67

To find the median, first we will arrange the given numbers in ascending order.

29, 51, 54, 60, 64, 66, 66, 67, 68, 75, 77, 80

So, the median will be

Hence, the median is 66.
