Slope

[beto]

"Do you want to take the average of these for each date, or the first,
or the last ???"

Both options would help me a lot, taking the average for each date and then
do the slope.
Also taking the first and last.

Please if you can tell me how to do it I would appreciate it a lot.
Thanks!

You have several values in column C for 8/25/2009 and for 8/27/2009.
Do you want to take the average of these for each date, or the first,
or the last ???

Slope is the change in Y divided by the corresponding change in X, or
in your case:

(Cn - Cm) / (An - Am)

so if you can explain which values of C you want to take for those
dates then it's quite easy to plug them into this formula.

Hope this helps.
