bekas [8.4K]

Answer:

The median is 5.4

Step-by-step explanation:

To find the median, you must arrange the numbers from smallest to largest:

1.7, 3.8, 3.8, 3.8, 4.8, 5.4, 5.4, 5.4, 5.4, 5.5, 5.9, 6, 6.3, 6.5, 6.6, 6.6

Since there is an even number of values, we take the middle to values and find the average:

5.4 and 5.4

Since the middle values are 5.4 and 5.4, the average of the middle is 5.4, making the median 5.4
