Solución
-
Understanding the Sample:
Edna surveyed the first 12 shoppers at the market. This means the sample includes the shoppers who arrived first, not a random selection of all shoppers. -
Analyzing Bias:
A sample is biased when it does not accurately represent the entire population due to a systematic error in the selection process. Choosing the first 12 shoppers is a form of convenience sampling, which can lead to a non-representative sample. -
Conclusion with Reasoning:
Because the first 12 shoppers might have characteristics (such as their schedule, preferences, or urgency) that differ from the rest of the shoppers, the sample is likely to be biased.
Therefore, the answer is:

Sampling just the first 12 shoppers at a market could introduce bias, as these individuals might be similar in their shopping habits or times of arrival. For instance, early birds tend to shop differently from latecomers, affecting the overall representation of the shopper demographic. A more random approach would yield a sample that reflects the diversity of all market-goers.
To mitigate bias in sampling, it’s essential to consider various factors, like the time of day or the specific day of the week. If Edna were to survey shoppers at different times or locations within the market, she would gain a more balanced view. Plus, making sure to include different demographics—like families, single shoppers, and seniors—can help ensure her findings are more generalized and reliable.
