Answer 1

Blindness.

Answer 2

just blindness or would cofounding be a choice too?

Answer 3

ohh wait check all that apply.

Answer 4

@satellite73 do u think confounding should be checked too?

Answer 5

im on edge about it, i looked up its definition and it meant 1.Cause surprise or confusion in (someone), esp. by acting against their expectations.
2.Prove (a theory, expectation, or prediction) wrong.

Answer 6

i thought this was called "double blind" but i am obviously wrong

Answer 7

yes it is. i think

Answer 8

no like i knew this was double blindness, but hmm confounding

Answer 9

That's kinda true too

Answer 10

i have never heard of "confounding"
the control i guess is the people receiving the placebo, but i really should be quiet because i am only guessing here

Answer 11

wow. it just told me the answers were control and blindness. this is crazy but i guess the computer knows best smh. thankkkkkkkkkkkkkssss guys i really appreciate your help. :]

Answer 12

Okay, it was definitely not confounding.. well kinda pointless now, but like confounding is when u have a hidden variable that screws up your results apparently. Just looked it up.
