Does someone have read the original article ?
I am curious about how the reader evaluation of potential risk was assessed.
Was there a control group which didn't see any comment to compare variance amongst this group to the other groups variances ?
How was the sampling done ? Were people with knowledge of science equitably balanced amongst groups ? How many of them was there ?
At which level is the variance difference amongst groups significant ? 2000 subjects can lead to average results depending of the sampling. The jsonline article does quite a lousy job with details. |
