Which of the following is a discrete quantitative (numerical) variable? . a) The Dow Jones Industrial average. . b) The volume of water released from a dam. . c) The distance you drove yesterday. . d) The number of employees of an insurance company
The correct answer is (d) The number of employees of an insurance company
The correct answer is (d) The number of employees of an insurance company.
A discrete quantitative variable is one that can only take certain specific values and cannot be measured on a continuous scale. In this case, the number of employees of an insurance company can only take whole number values, such as 10, 50, or 100, and cannot have fractional values.
Option (a) The Dow Jones Industrial average is a continuous quantitative variable as it is calculated based on the prices of multiple stocks and can have decimal values.
Option (b) The volume of water released from a dam is also a continuous quantitative variable as it can have any value within a range, including fractional values.
Option (c) The distance you drove yesterday is a continuous quantitative variable as it can also have any value within a range and can have decimal values as well.
Therefore, the number of employees of an insurance company is the only option that represents a discrete quantitative variable.
