Slope using dates
Hi, I want to get the slope from Column C using a certain range of dates from
Column A. I did this already for getting the max value, but I do not how to do it using Slope. Example I did using Max: =MAX(IF(ISNUMBER(MATCH($A$2:$A$500,M2:N2,0)),$c$2: $c$500)) M2=8/25/2009 N2=8/27/2009 "I need Slope" ColumnA ColumnB ColumnC 8/24/2009 345 34 8/25/2009 345 465 8/25/2009 567 566 8/25/2009 456 465 8/26/2009 456 876 8/26/2009 244 243 8/26/2009 123 264 8/26/2009 876 436 8/27/2009 678 134 8/27/2009 484 134 8/27/2009 356 654 8/27/2009 456 456 8/27/2009 234 123 8/28/2009 567 453 |

Slope using dates
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. Pete On Jan 25, 10:18*pm, beto wrote: Hi, I want to get the slope from Column C using a certain range of dates from Column A.

Slope using dates
"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! -- asdf "Pete_UK" wrote: You have several values in column C for 8/25/2009 and for 8/27/2009.
