Question

How can central tendency and interquartile range be determined in data sets?

Options:

A) Calculate the mean, median, and mode for central tendency, and then find the interquartile range by subtracting the first quartile (Q1) from the third quartile (Q3).

B) Find the mode for central tendency and subtract the range from the mean to determine the interquartile range.

C) Use the median for central tendency and calculate the range between the first quartile (Q1) and the third quartile (Q3) for the interquartile range.

D) Calculate the standard deviation for central tendency and determine the interquartile range by subtracting the mean from the mode.

Answer 1

Central tendency can be determined by calculating the mean, median, and mode, while the interquartile range can be found by subtracting the first quartile from the third quartile. Option A is correct.

Step-by-step explanation:

The central tendency of a data set can be determined by calculating the mean, median, and mode. The mean is the average of all the values in the data set, the median is the middle value when the data is arranged in ascending order, and the mode is the value that appears most frequently. The interquartile range (IQR) can be found by subtracting the first quartile (Q1) from the third quartile (Q3). The IQR represents the spread of the middle 50 percent of the data. So, option A is the correct answer.
