Average items in a List for specific time interval

[ambguy]

I have a List of items (type: double). Each item has it's own timestamp.

Now I need to calculate the average of items in a past interval. For example: Average of all items starting from 20 minutes ago until 10 minutes ago. Can someone suggest me how do I go about it?

Thanks a lot!

Where are the times for each item stored?

Average = Total/Count

Are you able to count how may records there are in that period?
Are you able to add the totals of the records in that period?

Good question and sorry for missing out on that detail.

Yes, I have a count of records from time = 0 to DateTime.Now().

I can also add any of these records.

My confusion is how to fetch items from my List for a specific time interval, say average of 5 minutes, from 10 minutes ago.

Loop through each item and check to see if the time is between the interval you're looking at.
