## K=the number of items in your test |

## M=the mean score on the test |

## s=the standard deviation of the scores on your test |

|
## How this all works: |
|
## Statistics are computed by calling &get_statistics with the sequence, |
|
## resource, and part id to run statistics on. At various places within |
|
## the loops which compute the statistics, as well as before and after |
|
## the entire process, subroutines can be called. The subroutines are |
|
## registered to the following hooks: |
|
## |
|
## hook subroutine inputs |
|
## ---------------------------------------------------------- |
|
## pre $r,$count |
|
## pre_seq $r,$count,$seq |
|
## pre_res $r,$count,$seq,$res |
|
## calc $r,$count,$seq,$res,$data |
|
## post_res $r,$count,$seq,$res |
|
## post_seq $r,$count,$seq |
|
## post $r,$count |
|
## |
|
## abort $r |
|
## |
|
## subroutines will be called in the order in which they are registered. |
