DATA

I have gathered quantitative data on the amount of time I spend using the computer on a daily basis. For ten days, I have collected data (number of hours) for a sampling. The procedure that I followed is as follows:

1. Record the time I log on to the computer.
2. Record the time I log off the computer.
3. Tally the total number of hours logged in at each sitting.
4. Sum up all the sitting time totals to get a daily grand total.
5. List the grand totals for each day.
