2. Give one example of a transportation decision that could be measured with a discrete variable.
Homework Answers
1) A continuous variable is that variables which can take all the values between two real numbers. There are infinite possible numbers for a continuous variable. In a transportation problem, if the rate is charged as per weight, then the weight is a continuous variable. Suppose maximum load a truck can take is 10 tons. Then, the weight can be any value between 0 and 10 tons and there are infinite possibilities.
2)
A discrete variable is that variable which can only take a value from a particular set of values. In transportation case, if the rate is charged per unit transferred, then number of units is a discrete variable. Units can only be whole numbers. Suppose maximum units is 100. It can take all whole number from 0 to 100 and there are 101 possibilities.

Is the quantitative variable discrete or continuous? The number of customers served in one day at the drive through in a local bank. The variable is discrete because it is not countable The variable is continuous because it is measured and not countable. The variable is continuous because it is not measured. The variable is discrete because it is countable
