Question

Please help I will give you a shiny medal :)



A simple random sample is always preferred because it obtains the same information as other sampling plans but requires a smaller sample size.

A. ​True, because it does not require extra preparation and can return more information than the other sampling techniques.
B. ​False, because other sampling techniques may provide more information for less cost than a simple random sample.
C. ​False, because simple random samples require a larger sample size than most other sampling methods.
D.​True, because every individual has an equal chance of selection.

Answer 1

I think it's D but I'm not sure, can you explain please?

Answer 2

I think it's A.

Answer 3

D looks right to me, as well.

Answer 4

Is this for a statistics class?

Answer 5

Hmm because I'm getting confused by this question, a simple random sample has every possible sample of a size 'n' to have an equally likely chance of occurring..

Answer 6

hmm D was incorrect..

Answer 7

It's definitely False.

Answer 8

I know! It's False because simple random samples require largeer sample sizes.

Answer 9

but how does it give more information than other sampling techniques?

Answer 10

A was actually incorrect :( A, The statement is false​ because, quite​ often, the goal is not to obtain the best​ sample, but to obtain as much information as possible about the population at the least cost. With this goal in​ mind, it may be advantageous to use sampling techniques other than simple random sampling. So it's either B or C...
