SLOPE did the trick! Thank you very much for your help, DanGSB!

Leotoni,
assign 1,2,3,..... to the months and have an array with the sales figures.
There's SLOPE function which gives the x-angle of the data series. Depending
on value you construct an IF statement so that user gets the STABLE... etc
info you want.

I am trying to create an IF formula that returs POSITIVE, NEGATIVE, or STABLE
depending on the trend found in a data series. Does anybody know how can I
evaluate a data series for a positive/negative/stable trend? For instance, I
have the following data set:

MONTH January,February,March,April
SALES 100,200,300,100

If I use a chart to analyze this data, I can visually identify it is a
positive trend. Can I get that simple answer using a formula, rather than a
chart?

Thank you!
