time formats

[hein68]

I have three time variables in the time8 format, like this:

id           mod1    mod2    mod3

232791 0:50:29 0:34:49 0:36:41
234068 0:40:50 2:28:09 0:36:08

I need to get means and standard deviations on the number of minutes.  What time format should I be using?

Thanks!

How do you want to do this? With PROC SUMMARY?

Also, do you want do do get the statistics by id, variables or overall?

I want to get the overall mean and standard deviation for the mod1, mod2, and mod3 variables.

I was hoping to create new time variables with a format so that when I do the summary statistics the results come out in minutes, something like 37.2 (minutes) mean +- 5.3 (minutes), standard deviation

thanks!

If you want to do calculations on minutes then you will need to convert your values from seconds into minutes by dividing by 60.

Yup that did the trick.  Thanks!!
