discrete variable, types of data2. Which of the following is a continuous quantitative (numerical) variable?. a) The color of a student’s eyes. b) The number of employees of an insurance company. c) The amount of milk in a 2-liter carton.. d) The number of gallons of milk sold at the local grocery store yesterday
The correct answer is (c) The amount of milk in a 2-liter carton
The correct answer is (c) The amount of milk in a 2-liter carton.
A discrete variable is a variable that can only take on specific, separate values. For example, the number of employees of an insurance company and the number of gallons of milk sold at the local grocery store are both discrete variables because they can only be whole numbers. You cannot have a fraction or a decimal for the number of employees or the number of gallons of milk sold.
On the other hand, a continuous variable is a variable that can take on any value within a certain range. The amount of milk in a 2-liter carton is a continuous variable because it can be measured and exist as a fraction or a decimal value. You can have 1.5 liters of milk remaining in a 2-liter carton, for instance.
So, out of the options given, (c) The amount of milk in a 2-liter carton is the only example of a continuous quantitative (numerical) variable.
