Question

multiple - choice question what is the median of this set of data? 16 19 17 18

Explanation:

Step1: Arrange data in ascending order

$17, 18, 18, 19$

Step2: Determine the middle - value

Since there are 4 data points (an even number of data points), the median is the average of the two middle - values. The two middle - values are the 2nd and 3rd values.
Median=$\frac{18 + 18}{2}$

Step3: Calculate the median

Median = 18

Answer:

18
