Sampling Plane
Our company use non probability sampling to take a sample from a large population because these process help us to take survey easily. we use convenience samples method to conduct questionnaires/mail-online survey and mall intercept as data collection because it fast, not expensive and easy to get data, distribute to customers and know the needs each age. Also easy to distribute the questionnaire, because we are not determine the age or gender, anyone can do questionnaire. The population is too large that we cannot collected all of them. This is the reason why we use this method.
