Question

which of the following is the most biased type of sample? systematic sample random sample convenience sample

Explanation:

A convenience sample is a non - probability sampling method where the sample is taken from a group of individuals that are easy to reach or access. This can lead to a sample that does not represent the entire population well. For example, if a researcher wants to study the opinions of students in a university and only samples students from one particular class (because it is convenient), this sample may not have the same characteristics (such as age, major, etc.) as the overall student population. A random sample is a probability sampling method where each member of the population has an equal chance of being selected, which is less likely to be biased. A systematic sample also has a more structured and less biased approach compared to a convenience sample as it follows a fixed pattern (e.g., selecting every \(n\)th element from a list).

Answer:

convenience sample
