Answer 1

We will go through the answers one by one.

a) This is an observational study as there are no different groups involved in this. This study takes data of how much time a kid spent time indoor and how many friends he has.

b) Daniel's population should be all the kids.

c) Daniel's sample is 20 kids in a third-grade class

d) N/A as an observational study has no independent variables.

e) N/A

f) N/A

g) N/A

h) Daniel is interpreting interpersonal skills as the number of friends the kids have.

i) The operational definition of interpersonal skills may be different for different people. To get the correct variables for interpersonal skills you should experiment with different variables like what kind of school kid is studying, how much time he is spending in school etc. So being specific about the operational definition is very important.
