Spearman's Rank Correlation Coefficient Watch

    • Thread Starter


    Doing some statistics coursework, I have no problem with working out SRCC but can't understand what to do if I have n/a data for some parts as women didn't compete in the olympics or world championships nor could I find any data for this. What do I do with this n/a data do I still rank it??? Also what do I do with data which is the same (eg. 46.2 seconds) As shown below....

    400 metres times

    Year Men Time (s) Women Time (s)

    1900 49.4 n/a

    1912 48.2 n/a

    1924 47.6 n/a

    1932 46.2 n/a

    1948 46.2 n/a

    1960 44.9 53.5

    1972 44.66 51.08

    1984 44.27 48.83

    1996 43.49 48.25

    2008 43.75 49.62

    Help would be very appreciated,


    I think the best thing to do for statistical integrity would be to replace that sample with a different sample in which women did compete (although this might be difficult considering the specifics of the question) - as it stands, you either should ignore the results from 1900-48, or perhaps replace them with different athletic events (although you would probably need to expand the scope of your entire coursework to do this)?

    As an aside, why on earth are you doing statistics coursework with such a small population?
