Q₂ = 78

Step-by-step explanation:

Q₂ is the median of the data set.

The median is the middle value of the data arranged in ascending order.

If there is no exact middle value then it is the average of the values either side of the middle.

48,  64,  66,  70,  72,  84,  86,  90,  92,  94 ← in ascending order
