Week One Summer 2010 Shortcourse : Math in Science Context: Assignment Questions Post Answers: "Questions for Wed: These are some questions regarding density that could go on the blog. 1. Did the true value for density fall within the ..."
Our true value for Copper's density did not fall within the confidence interval. Our experimental value did fall within the confidence interval which tells us that we were 90 - 95 % true to the actual value??
Question 2: The interval increases as the confidence level percentage increases. If you were trying to hit a target with 95% confidence as opposed to 90% confidence, the target would need to larger to get within the 95%.
Question 3: I believe if one made a determinant error on the first measurement, it would not effect subsequent measurements. More trials are used to decrease the human error.
Question 4: Power output = 0.099W/m^2
(using P=k4pie)
Question 5: I use lab quests and some probes. Would like to do more probe work. Having used the blog, google docs and excel these past two days, makes me want to try to use it with my students - especially Physics. I have tried some palm activites and computer driven assignments in the past but found that time and room became a problem. Our wireless connection in our school is not great and hard to get software accessible for student use.
