Answer 2

On my teachers pop quizzes, I do so well... but when it comes to these, I always get B's and C's :(

Answer 3

Thank you, you are a life saver :)

Answer 4

Im thinking B.

Answer 5

My sister says its A but idk why

Answer 6

yay :)

Answer 7

I asked Jessica and she said A

Answer 8

Stratified sampling makes allowance for known differences within the underlying population. So A is not the technique that was used.
Simple random sampling is equivalent to each member of the parent population having an equal probability of being selected; also each selection must be independent of the others. So B is not the sampling technique that was used.

Answer 9

Then that only leaves D.

Answer 10

Systematic sampling entails choosing each member of the sample by ordering the sample frame in some way; then individuals are selected at regular intervals. An example is taking a 1% sample of telephone subscribers by selecting the 31st, 131st, 231st (and so on) of the names in the telephone directory. So systematic sampling is not the technique that was used.

Answer 11

my final answer is Cluster?

Answer 12

sorry for being wrong a lot :(

Answer 13

I'm really trying my best.

Answer 14

Not a problem. The choices left are Convenience sampling, Census and Cluster sampling.
A census is a 100% survey. Do you think that the principal took a census?

Answer 15

yes, it said that they took surveys

Answer 16

would that be it?

Answer 17

A survey is what each student had to fill in. Not all of the students in all of the English classes were chosen. Therefore a census was not taken.
Now the choices are Convenience or Cluster sampling.

Answer 18

Would it be convenience?

Answer 19

it would be convenient to choose because the proximity of them is just the English Classes where then can be easily found.

Answer 20

I think that Cluster sampling was used. This method of sampling entails choosing the members of the sample from one or several groups {clusters) instead of selecting at random from the entire population.
Convenience sampling is also known as Opportunity sampling. Convenience sampling is unstructured when compared with Cluster sampling.
