They also work when t-tests aren't giving good results.

I thought they were only for small sample sizes?
EL

Wait, are you sure they don't need normal distribution?
BE

Totally agree, especially when medians are involved.

Non-parametric tests are great for non-normal data!

I’m a bit confused about option A; I thought t-tests could still be used in some cases, but maybe they don't work well with small samples?
RO

I feel like I’ve seen practice questions where they emphasized that non-parametric tests don’t rely on normality, which makes me think C is definitely right.

I remember something about testing the median, so option B might be one of the answers, but I'm not entirely sure.
TI

I think non-parametric tests are used when the data isn't normally distributed, so maybe option C is correct?

This is a good opportunity to show my understanding of non-parametric methods. I know they're useful when the data doesn't fit the normal distribution assumptions, and for testing hypotheses about medians. I've got a solid strategy for this.

Wait, I'm not sure about the "no parameters" part. I thought non-parametric tests still had parameters, just different ones than parametric tests. I'll have to think this through step-by-step.

Okay, I've got this. Non-parametric tests are used when the data doesn't meet the assumptions for t-tests, like normality. And they focus on medians rather than means. I'm pretty confident I can nail this one.

Hmm, I'm a bit confused on the differences here. I know non-parametric tests don't require normal distributions, but I'm not sure about the other criteria. I'll have to review my notes carefully.

This looks like a tricky question, but I think I can figure it out. I'll need to remember the key differences between parametric and non-parametric tests.

I heard the exam committee was considering adding a 'choose all of the above' option, just to keep us on our toes. Non-parametric testing is like the party animal of statistical methods - it'll show up to the test, but it might not remember the answers.

C) It does not require data to come from Normally Distributed populations

Ah, the joys of non-parametric testing. It's like trying to hit a moving target with a blindfold on. But hey, at least we don't have to worry about those pesky normal distributions, right?
RO

Haha, looks like the exam writers are trying to trick us with this one. I'm going with B, C, and D - can't go wrong with multiple correct answers!

User 3: I'm going to go with A, B, and D just to be safe.
NA

User 2: Yeah, I agree. Non-parametric testing is definitely used when data doesn't have to be Normally Distributed.
DA
Daniela

User 1: I think B, C, and D are the correct answers too.
AS

I thought non-parametric tests were used when we don't know the parameters of the population. Option E looks like the right answer to me.
TR

User 3: They also look at the Median rather than the Mean of populations.
DO
Dolores

User 2: That's correct. Non-parametric tests do not require data to come from Normally Distributed populations.
CA

User 1: Non-parametric testing is done when there are no parameters to measure in the process.
DE

I'm pretty sure non-parametric testing is used when the data doesn't follow a normal distribution. Options C and D seem to be the correct answers here.
TO
Tori

So options C and D are the correct answers for when non-parametric testing is applicable.
AR
Aracelis

It also looks at the Median rather than the Mean of populations.
LA

Yes, that's correct. It doesn't require data to come from Normally Distributed populations.

I think you're right, non-parametric testing is used when the data doesn't follow a normal distribution.
AL

I believe non-parametric testing is done when data doesn't have to be normally distributed.
KR

I agree with Antonette, it's also used when looking at the median instead of the mean.
AN

I think non-parametric testing is used when traditional t tests don't work.
