Question

Subway wants to collect data about employee satisfaction within its organization. It decides to survey a sample of 500 employees by having a computer program automatically pick which employees will be in the sample. If it uses the payroll database as the list of names to chose from, which type of sampling method is Subway using?

Answer 1

Random sampling

Explanation:

Subway is using a random sampling, since a computer program automatically will pick which employees will be in the sample and the payroll will be used as the list of names to choose from, we can say that 1) the selection of employees will be based on chance and 2) ALL employees have a chance of being selected (all employees are in the the payroll database).

These two conditions are the characteristics of random sampling.
