Question
What is the median of the dataset: 6, 9, 12, 15, 18, 21, 24, 27, 30, 33?a.17b.18.5c.19.5d.20
Solution 1
To find the median of a dataset, we need to arrange the numbers in ascending order.
The given dataset is: 6, 9, 12, 15, 18, 21, 24, 27, 30, 33.
Arranging these numbers in ascending order gives us: 6, 9, 12, 15, 18, 21, 24, 27, 30, 33.
Since the dataset has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 18 and 21.
To find the average, we add the two middle values and divide by 2: (18 + 21) / 2 = 39 / 2 = 19.5.
Therefore, the median of the dataset is 19.5.
The correct answer is c. 19.5.
Solution 2
