A Formual for trends?

[marlyn]

I need to figure out how to see the trends in my data.<br>

I'd like to be abled to find out how many people have improved in my overall data and then I would like to know which individual has improved. If you could please help me or send me to someone who can i would greatly appreciate it.

you first have to establish what you mean by &quot;improved&quot;: as measured against a person's previous score(s) or against the group.<br>
is the expectation that each score will be higher than the previous one [then simply do a series of comparisons by subtracting the older from the newer], or that overall a person has done well [take the min and max values; subtract them from the avg value].<br>
while i'm not a statistician, i do know a trend involves an outside benchmark against which your values can be measured. (for example, after a review class you notice scores start going up. so the trend will have to be two dimensional: scores versus time )[i may be going in more deeply than your question needs...]<br>
