What is the value of the first quartile for observations 15, 18, 10, 2...
Finding the First Quartile:
To find the first quartile, we need to arrange the given data in ascending order.
10, 12, 15, 16, 18, 20, 23, 28
The first quartile is the median of the lower half of the data set. Since there are 8 observations, the middle observation is the 4th one, which is 16. Therefore, the first quartile is 16.
Answer Explanation:
Option C is the correct answer because it is the value of the first quartile of the given data set. The other options are either incorrect or do not provide any useful information.
