Question

which of the following is a survey given to those who are easy to contact?
convenience sample
random sample

Explanation:

A convenience sample is a non - probability sampling method where the researcher selects individuals who are easily accessible or convenient to contact. A random sample is selected in a way that every member of the population has an equal chance of being chosen. A systematic sample is selected by choosing a starting point and then selecting every \(k^{th}\) element in the population. A self - selected sample is one where individuals volunteer to be in the sample.

Answer:

convenience sample
