Question

Kim and Tracy are collecting data for their final project in their psychology class, in which they are conducting a survey about people's overall job satisfaction. They decide to go to the local mall to collect their data. To get a more varied sample, Kim surveys shoppers coming out of store A, a discount clothing store, while Tracy surveys shoppers coming out of store B, a high-end boutique

A. Identify a possible problem with this type of sampling method.

B. How might Kim and Tracy improve on their sample design so as to get more accurate information?

Explanation / Answer

A.) In this type of sampling all the data that Tracy collects will not be random as at a high end boutique shop there will be only rich people coming in. And so most of them would be job ssatisfied by their jobs.

B.) Kim and Tracy could collect the information from any random person coming in the mall. This would include any person from lower income groups to high income people and will lead to a more randomized data.
