liza wanted to know which brand of basketball shoe high school basketball players preferred. she grouped the list by boys and girls, and chose 70 boys at random and 70 girls at random. she decided to ask the girls in her team. what type of bias best describes the error in her sample? selection bias, sampling frame convenience bias, incorrect sampling frame systematic sampling bias, sample non - response bias, population
Answer
# Brief Explanations:
Liza chose the girls from her team for the sample, which is a convenient - but not representative - way of sampling. This is convenience bias as she selected based on ease of access rather than a proper sampling method. The sampling frame (the list from which she samples) is also incorrect as her team is not a good representation of all high - school girl basketball players.
# Answer:
B. Convenience bias, incorrect sampling frame
