Show Suggested Answer Hide Answer
Suggested Answer: D

The sample used in this case is biased, meaning that it is not representative of the population of interest. The population of interest is the families in North America, but the sample is drawn from only one source of data: the credit card transactions from a leading North American credit card company. This sample excludes the families who do not use credit cards, or who use other credit card companies, or who use other payment methods. Therefore, the sample is not random or fair, and it may introduce sampling bias into the research results12 Reference: 1: Sampling Methods | Types, Techniques & Examples 2: Sampling Bias - an overview | ScienceDirect Topics

I think the sample might not be relevant since it only reflects one company's customers, but I need to double-check what makes a sample representative.

I feel like using only one credit card company's transactions could introduce bias, but I can't recall the exact definition of biased sampling.

This reminds me of a practice question where we analyzed sample sizes. I think if the sample is too large, it could lead to issues, but I'm not sure how that applies here.

I remember discussing sampling methods in class, but I'm not sure if using just one company's data makes it statistically representative.
