I’m not a pro, but you probably want to turn the data into a z-score (this class is ranked 3 standard deviations above the ranking for other self-help classes). If you can’t turn it into a z-score, the data is probably meaningless.
Also, maybe use some other ranking system. I imagine that people have a mindless cached procedure for doing these rankings that you might want to interupt to force acually evaluating it (rank is a random variable with mean = 7 and stddev = 1).
