Answer:
Explanation:
To find the median of a set of data, you first need to arrange the numbers in either ascending or descending order. Once the data is arranged, the median is the middle value.
Let's arrange the data in ascending order:
20, 34, 36, 38, 39, 40, 46, 72, 85, 92
Now, there are 10 numbers in the dataset. Since the number of observations is even, the median is the average of the two middle values. In this case, the fifth and sixth values are 39 and 40.
So, the median is:
Median
=
39
+
40
2
=
79

=
39.5
Median=
2
39+40
=

79
=39.5
Therefore, the median of the given data set is 39.5.
