Identifying data from specific time periods

Question

0 个投票

Hi, I have data which represents a persons activity over 5 consecutive days. I want to try and identify data from specific time periods e.g. there activity between 3pm-8pm on Wednesday and between 9am-1pm on Friday. Any suggestions on how I can do this? Thanks

Huh? What does it mean to you to identify data? Explain your question CLEARLY. Give an example.

With so little information, how can we answer?

Is the timing of the activity stored in your data? If not, is the activity measured at a regular interval (which is ...?). Basically how do you know what the activity timing is?

Thanks Guillaume. The activity has been classified as either active (1) or not active (0) in Matlab, for the whole 5 day period (120 hours), with a measurement being taken every tenth of a second. So I can calculate total active and non-active time for the whole 5 day period, but I would like to specifically look at certain times of the day. Is that a bit clearer?
