Question
Noah surveyed the 47 customers in a shoe store on a Monday morning.Is this sample of the shoe store's customers likely to be biased?
Solution
To determine if the sample is likely to be biased, we need to consider a few factors:
-
Time of Survey: The survey was conducted on a Monday morning. This could potentially introduce bias as it may not represent the entire customer base of the shoe store. For example, people who work typical office hours may not be able to shop on Monday mornings, and thus, their preferences would not be included in the survey.
-
Size of Sample: The sample size is 47 customers. Depending on the total customer base of the shoe store, this may or may not be a large enough sample to accurately represent the population. If the store has a large customer base, then 47 might be too small to get a representative sample.
-
Selection of Sample: The text does not specify how the customers were selected for the survey. If they were randomly selected, then the sample is less likely to be biased. However, if they were not randomly selected, there could be a selection bias.
In conclusion, based on the information given, there is a possibility that the sample could be biased due to the time of the survey and potentially the size and selection of the sample. However, without more information, it's hard to definitively say if the sample is biased.
