So what if it is in relation to statistics?  You can still write a statistical function or make a linear curve approximation.  Are you familiar with using calculus on statistics @Anna904?  Did you have specific example question?

anonymous · Answer

here's the problem:
- out of 1112 trading days in this period, the average increased on 573 days (sample proportion of 51.53%)
- is the dow jones industrial average just as likely to move higher as it is to move lower on any given day?
- perform a test at alpha=.05 significance level.
