What is the value of the first quartile for observations 15, 18, 10, 20, 23, 28, 12, 16?(a) 17 (b) 16 (c) 12.75 (d) 12
Question
Solution 1
To find the value of the first quartile, we need to arrange the observations in ascending order: 10, 12, 15, 16, 18, 20, 23, 28.
Since we have 8 observations, the first quartile is the median of the lower half of the data set. In this case, the lower half consists of the first 4 observations: 10, Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
