Hello,
Thanks Jasen Betts. Did you mean the difference between the maximum and minimum of number of registrations divided by the time interval? If I got the following number of registrations in a week as
Survey Date NoOfFeverCaseRegistrations
12/07/09 30
13/07/09 70
14/07/09 20
15/07/09 90
16/07/09 40
17/07/09 50
18/07/09 20
Although the survey does not indicate a steady increase of fever cases during this week, there is a tremendous increase on dates 13/07/09 and 15/07/09. Considering the whole week, I feel I should say there is an unusual increase in number of case registrations. How I can I do this. Can I use any statistical deviation measure for this? Have a great day. Thanks.
