A and D Of course

Answer 7

it says which of these of "EXPERIMENTS" are NOT characteristics of surveys

Answer 8

in my notes it says about surveys:
While experiments generally compare two or more treatments that are applied to experimental units or subjects, with surveys there is no treatment to be researched.

Answer 9

so does that have anything to do w/ what option C says in parentheses?

Answer 16

Let's go through the process of elimination:
It cannot be A, because we know that statistical analysis is always applied to the results of the study.

Answer 17

tbh, I think it's B and C, unless you're conducting a very specific survey.

Answer 18

You usually don't really have these various groups. You just have a big population/sample

Answer 19

yea because the options they give u above are all characteristics of experiments but u need to figure out which ones aren't characteristics of surveys right

Answer 20

Yea

Answer 21

so this is what my notes say:
Like experiments, surveys rely on collecting and analyzing data. But while experiments generally compare two or more treatments that are applied to experimental units or subjects, with surveys there is no treatment to be researched.
A survey attempts to draw a conclusion or make an inference about a population parameter, based on statistics gathered in a relatively small sample from the whole population.

Like experimenters, surveyors or pollsters must be concerned with sources of bias in their research, and use the appropriate statistical techniques to minimize these errors. Only then can they be confident that their experimental conclusions or survey results are accurate, and not unduly influenced by chance or bias.

Answer 22

So then it is B and C.

Answer 23

hey I had c down too!!

Answer 24
