so.....i guess it's systematic

Answer 4

okay
systematic sampling is when you develop a system and follow it to to collect your data. If you choose every 5th person, that would be systematic

Answer 5

CLuster sampleing is when you randomly section off a group and then sample them

Answer 6

Random sampleing is when you randomly select people with no describable order

Answer 7

Convenience sampling is when you select whoever would be the easiest to sample. You make no attempt to assure the sample is an accurate representation. This sample would be bias.

Answer 8

Stratified sampling is when you take a population. Divide it into a subgroup based on some characteristic. Then sample that entire subgroup.

Answer 9

Which one do you think it is?

Answer 10

*hint* its not systematic

Answer 11

This is best described as stratified. The population of the college was divided into strata, namely freshman, sophomores, juniors, etc. Then, some sampling technique is applied to the stratum.. but in this case the entire stratum was selected... so no further sampling method was applied.

Answer 12

you had to give it away didnt ya

Answer 13

sorry, i am new at this.. aren't we supposed to give away answers while provided an explanation? Or, is it best practice to only lead other uses toward finding the answer for themselves? I guess I am assuming that users have tried and tried on their own already, and coming here is their last effort to find a solution.
