Answer:

A) 3/25

Step-by-step explanation:

Answer:

Step-by-step explanation:

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

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

Arrange the data in ascending order

1, 4, 6, 8, 8, 9

The middle is between 6 and 8, thus

median = $\frac{6+8}{2}$ = $\frac{14}{2}$ = 7
