Baseline (graph)

Time frame for measurement of initial baseline: 28 Sep - 11 Oct
Average amount of time spent on computer daily from 6pm - sleep time: 245.43 minutes
Highest value recorded: 115 minutes (5/10/08)
Lowest value recorded: 482 minutes (10/10/08)

Baseline (description)

I have identified the behavior to be measured as the amount of time spent on the computer after 6pm daily. The unit of measure would be in minutes.

The timing was chosen to be from 6pm - sleep time daily as
1) The time spent in school (and consequently the time spent on the computer during the morning and afternoon) differs for different days of the week. To ensure comparability among the data gathered, only the time spent on the computer after 6pm is recorded (6pm being the time after which there are no lessons).

2) There is no initial evidence to suggest that the time spent on the computer from 6pm - sleep time differs between a weekday and a weekend (and hence the behavior is measured on all 7 days of the week).

Procedures for measuring baseline:

1.Open up the excel file "HP320" immediately after logging in to the computer (prior to commencing any other activities eg. logging in to MSN)
2.Record the day and timing of log in
3.Record the timing of log off just immediately before shutting down the computer
