Answer B
What did you include there? The lab assistant said that it was impOl1ant to be specifIC when we did this part
Yeah, he did So I mentioned that there were ten subjects, and five wore drinking gin and tonic, but the other five that's the control gl'OlJp they ware drinking tonic only, and no one knew which group was which Then they each had to drive In a computer· ized • what was it called? A a slmulator •• a simulator ot a car that was supposed
to bo moving at 35 milo, an hoor And whon they saw B bicyGla, they wero supposed to
hit the brakes
more about the subjects think they were college students, end they were selected et random to be In the oxperimontal or control group
But you still have to explain the chart in the results section Vou do?
Veah Urn, look here's what rd do I'd look at the cnart ,",It~
lor the subjects who were drinking only tonic, and that's compared with 3 seconds to 20
seconds lor the subjects who were drinking gin with the tonic
So , I'm really just repealing whafs on the chart, but I'm elqllalning it in words Right But, here's the thing- you shouldn1 draw any coodusions In the results section
Just the facts Vou mean, just what happened in the experiment
Right ~tl!M! ~1ht~!iii!ii: fOr b!3!I!R • ~ Okay So in the conclusions, I might say that driving after naving lour drinks it you have lour drinks you probably won1 be In a position to avoid an accident
That's good And you could also point out problems In the research, If there are any, or suggestions for future research
Uke doing the experiment with beer Instead 01 hard liquor or repeating the same exper· iment with three drinks Instead 01 foor
Sure That's the idea
