OPEN ENDED Give examples of a biased sample and an unbiased sample. Explain your reasoning.
This is unbiased or not a random sample since it depends on each students understanding and they may also like some other subject rather than mathematics.
So this woman's labeled open ended for a reason. There's a lot of answers you could give. So there really isn't a way for me to tell you, Um, exactly what your answer should be. You've got a ton of options. The idea is you just need to give examples between a bias and bias. Um, bias would mean that whatever you are doing, your survey on the group you're picking from does not represent everyone years survey is supposed to represent. Unbiased would mean that whatever you're serving about, every person in that group has an equal chance of being picked. So I don't know. Um, let's say you are doing a survey about your school. Okay? If you're doing a survey about your school, an example of being unbiased would be you pick from everybody in the school. Meaning, um, pick from a roster of every student in the school roster of every student in the school, whereas being biased would be You know, uh, you could just Onley pick from people in your class, pick from only students in your class. You could I don't know, pick on Lee juniors. All right. Anyway, that you could limit your group, you could pick Aulnay girls or only boys anything. You could do that with. Limit to where not everyone in the school had a chance of getting picked. That would be biased. You could talk about you know what's football fans? Favorite team, right? If you want to be unbiased, you'd have to ask every football fan from all different parts of the world. If you want to be biased, then just ask people in your hometown because they're probably gonna be slave, uh, biased towards whatever team is closest to your hometown, right? It's not gonna be perfect. There will be people that are fans of teams that are not close to your town, but you're probably going to get more of a shade towards whatever the local team is. Anything like that. I mean, biased is what is what is not giving a fair representation. Unbiased means you are being random. You are being fair
