Asks:  I changed one of my solutions, and I have implemented it from last Monday(June22). I know I have to update my control chart with new data, should I show the data from this new solution is a different color?   On: 6/30/2009 2:50:22 PM5482  290Other290 Answer: Yes that would be a good idea. You can use the data till this intervention as pre-intervention period and the data after as the post intervention period and this will allow you to see if the intervention is making a difference. Of course, you can also examine if the combination of your three interventions are making a difference, in which case you do not need to change the pre- and post intervention times.

56785463 Answer: Delete This is a reasonable question. Many people cannot change elements of their environment. The first step is to recognize these elements and their influence in your habits. The second step is to try to change how these elements affect you. For example, I might work far away from my home and therefore have long commute during which I am inactive. Obviously I cannot easily change my home or my work so what can I do? I might be able to change times I commute so that I can avoid traffic and reduce my commute. I might do errands before coming home (e.g. shopping for food) which will take me out of rush hour. I might go to exercise after work, thus changing commute time. I might be able to build physical activity during commute (e.g. by biking portion of the commute, parking far away from work and walking). The point is that there is a lot I can still do even though I am stuck with where my home is and what work I do. Date of Answer: 6/13/2009 5:33:23 AM  Farrokh Alemi, Ph.D. 0

4129salma.elazem@gmail.com  Tukey Chart Making the storyboard was fun, and it was nice to see everything we went through and combining it together. Tukey Chart was the hardest, and honestly I still do not know how to complete it.   Delete Minute Evaluation  5  7/3/2009 11:41:34 AM  290  HSCI

4128kirvin@gmu.edu  Introduction to Causal Analysis i thought that the slide show was much more helpful than the book about explaining what was a cause and what was a goal. however i do wonder can the cycle of cause and effect continue in a circle like our process chart?  Delete Minute Evaluation  4  6/30/2009 11:06:01 PM  290  HSCI

4127cschumak@gmu.edu  Tukey Chart At first I had some confusion with the definition of the figures between the website and the book. Figure six in the book and figure 6 on the website are different.   Delete Minute Evaluation  3  6/28/2009 11:42:45 PM  290  HSCI

4126lassidmi@gmu.edu  Tukey Chart This was by far the most effort I put in an assignment, it was because I did a Tucky's chart from my own data and not from the given data in the web page. Thankfully I understook what I was supposed to do. I learned a lot about excel from this topic, Thank you!  Delete Minute Evaluation  5  6/28/2009 10:40:29 PM  290  HSCI

4122kirvin@gmu.edu  Tukey Chart I think a new video needs to be made for how to create a tukey chart b/c the new excel 2007 is very different and the video isn't 100% accurate.

4120vcheng1@gmu.edu  Tukey Chart During the last two sessions, not only did I learn more about systems analysis using my own data but I also learned how to use Excel 2007 by constructing control charts and tukey charts.
