You also provided ratings on six attributes about your dates: The participants filled out survey questions when they signed up, including what they were looking for in the opposite sex and what they thought others of their own gender looked for. Let's first find out how successful those speed dating events were.If you take the mean ratings and then subtract the self-rating from the peer rating, you see that participants thought others were more into looks while they were also into sincerity and intelligence. If both you and your partner request another date after the first one, then you have a match.
Interesting article, but surely the data set would have been more useful to us if they'd been considerate enough to include "matlab programming" and "data analysis" in the interest category ratings. On a more serious note, for histograms with non-uniform bin widths it's generally good practice to scale the areas rather than the heights, so perhaps the pdf normalisation option would be more appropriate. So far I have only one experience getting somewhat positive response from a lady by mentioning "MATLAB", and I think she was an astrophysicist at MIT.
The second chart gives the impression that the mode of the % matches distribution is around 15 rather than 0.
The data comes from a series of heterosexual speed dating experiements at Columbia University from 2002-2004.
In these experiments, you each met all of you opposite-sex participants for four minutes.
We should also remember that the data comes from those who went to Columbia at that time - as indicated by such variables as the field of study - and therefore the findings may not generalize to other situations.
