Question

1. how is the median of a data set determined?

a. by finding the most frequent value
b. by subtracting the smallest value from the largest
c. by identifying the middle value in an ordered set
d. by calculating the average of all data points

Explanation:

• Option a: Finding the most frequent value is how the mode is determined, not the median.
• Option b: Subtracting the smallest value from the largest gives the range, not the median.
• Option c: The median is indeed found by identifying the middle value in an ordered (sorted) set of data. If there is an even number of data points, it is the average of the two middle values.
• Option d: Calculating the average of all data points is how the mean is determined, not the median.

Answer:

C. By identifying the middle value in an ordered set
