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.
In statistics, a discrete variable is one that can only take on specific, separate values and cannot be measured on a continuous scale. In this case, the number of employees of an insurance company is a discrete quantitative variable because it can only be a whole number. You cannot have a fractional or continuous value for the number of employees; it is counted in whole units.
