They walk out. And as they are walking out, they tell them, oh just by the way,
these chocolate chip cookies, they are for the next experiment. So if you don't mind, don't touch them.
So you are sitting there, almost dying, but you are not touching it.
And ten minutes later, the experimenter does come in, takes you to the experiment.
The experiment is very difficult. Very difficult.
Very difficult test that you need to take. A test that most people don't solve
and requires a lot of perseverance and hard work. But most people, even with perseverance and hard work do not solve it.
So the outcome measure, what the researcher is interested in is mostly how much did you persevere before giving up on that test.
How much did you persevere before giving up on that test?
That was the outcome measure, the dependent variable.
Second group, randomly picked, come into the same room, sitting on the same chair, have the same bowl on the table.
But instead of chocolate chip cookies, what they have in the bowl are red beetroots.
Freshly baked. Just came out of the oven. And they are sitting there.
And the experimenter is about to walk out, says, just one more thing.
If you don't mind, don't touch those beetroots. They are for the next experiment. OK. Fine.
