Side question from the astronomy, but it's about data
Hi guys!
You have helped me before with astronomy and so on, but here is one question that I draw a blank as of now and it's about analytical chemistry, and I still don't get it. Thank you all in advance even if you can't help that much at all. Anyhow here is the question. 2 different photo radar detectors, each designed to identify speeding motorists, were being evaluated by the city police department. Each claim to be the best on the market. The speed observations made are as follows. Detector #1: red mini van=77. white station wagon=85. black truck=46. blue s.u.v.=155. silver motorcycle=92. Detector #2: red mini van=85. white station wagon=80. black truck=52. blue s.u.v.=150. silver motorcycle=100. All units are km/hour. Now the question: are the results from one model unique compared to the other, justify your answer, show calculations, and assumptions. We just started the course and we have spent most of the time talking about statistics, basic stuff like the mean and the standard deviation, but for those to be useful, I'd need more results right, more than just one number? So I don't know what techniques to use here that are by my assumption, supposed to be within the range of the basic statistics. Thank you for giving me any leads so that I can do something with this assignment. I posted here because there is lots and lots of astronomical data and I am just wondering if any of you had a chance to actually deal with it in a way that it's presented here, for one thing, one piece of data and then I am supposed to find out each model's uniqueness and what not? Thank you. |

N/m I think I got it.

How come things were labled with so much detail instead of just a,b,c,d,e
lol I guess you are learning about chi-square test? ....and would be much more tough if some assumption such as black and silver cars are harder to detect and which one has better quality But all this would be just fun excercise and not part of homework 8-) "Zarkovic" wrote in message news:Zdqgb.34834$6C4.30634@pd7tw1no...
