It says which of the following statements about operational definitions are true? there should be three that would apply.
00:09
So looking at this first one for familiar psychological constructs like attitudes or altruism, operational definitions are not necessary.
00:17
So that would be false.
00:19
So we're gonna put an x through that.
00:23
It is gonna be necessary, so that's why that would be false.
00:26
X1 operational definitions are more specific than conceptual variables.
00:31
That would be true.
00:32
So we're gonna give that a check mark.
00:37
Operational definitions can vary as to how well they represent conceptual variables.
00:43
That also is true.
00:45
So we'll give that a green check mark.
00:48
Next, researchers only need to operationally define their independent variables...
