Question

suppose one hundred eleven people who shopped in a special t - shirt store were asked the number of t - shirts they own costing more than $19 each.
bar chart with x - axis: number of t - shirts costing more than $19 each (0,1,2,3,4,5,6,7), y - axis: relative frequency (0, 10/111, 20/111, 30/111, 40/111) and bar heights: 1: 5/111, 2: 17/111, 3: 23/111, 4: 38/111, 5: 25/111, 6: 2/111, 7: 0
if the data were collected by asking the first 111 people who entered the store, then what is the type of sampling?
○ stratified
○ convenience
○ simple random
○ cluster

Explanation:

Convenience sampling involves selecting samples based on ease of access. Here, the first 111 people entering the store are chosen because they are readily available, fitting the definition of convenience sampling. Stratified sampling divides the population into groups and samples from each; simple random sampling gives each member an equal chance; cluster sampling samples entire groups. None of these match as well as convenience sampling here.

Answer:

B. convenience
