I thought A was the best example, but B makes sense too!

Wait, are we sure D is biased? Nokia's pretty reliable.

I’m a bit confused about this. I thought bias was more about how the sample is chosen, but I guess all these options have some bias.

I think option D is a clear case of bias because it only uses one model for testing. It doesn't represent all GPS models.

I'm not entirely sure, but I feel like option B could also be biased since it only tests one model of razor. Isn't that a form of bias too?

I remember we talked about sampling bias in class, and I think option C might be the best example since it only considers a specific group of participants.

I'm a bit confused by this question. The options all seem to involve some kind of sampling, but I'm not sure which one is the best example of bias. I'll have to think it through carefully.

Option C looks like the best example of bias to me. Selecting only the top finishers at a wrestling event would clearly skew the sample and not represent the full population.

Hmm, this is a tricky one. I'm not totally sure about the differences between the options. I'll have to read through them again and try to spot the key details that indicate bias.

This seems like a straightforward question on bias in sampling. I'll need to carefully consider each option and think about which one best represents a biased sample.

Option C is the way to go. Measuring only the winners is like baking a cake but only tasting the frosting!

I'm going with C. Excluding the majority of the wrestlers from the weight testing is a clear case of sampling bias.

Yeah, that could also introduce bias if they're not consistent in their measurements.

That's definitely a biased sample. They should have included all participants.

I'm not sure, but I think C might be the right answer. Focusing on just the top finishers doesn't seem like a representative sample.

Option C is definitely the best example of bias in sampling. Measuring only the top wrestlers skews the results towards a specific subset of the population.
