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.

Statistics

Using the data you have been collecting below, please do the following:

Using Excel, prepare a frequency distribution from the data you've been collecting.

Calculate the Standard Deviation of your data.

Is this a normal distribution?

What are the implications?

Write a 2 page paper (could be more if you want).
