Unformatted text preview: wers to the previous questions. As I said in my answer to the question , “How accurate can you be?”, I am assuming that “my reaction time” is a real, calculable quantity. So we measured the distance I let the ruler fall before I was able to catch it; from that, we calculated the average Jake Mokris (with Ji Kim) Group 0 September 18, 2011 time it took me to catch the ruler. And we did this experiment twice: once while I was distracted, and once while I wasn’t. Question 2: Show the relevant steps in your calculations. So, in this exper do. In order to get values for these, I have to get the averages from my data. Note that this derivation answers question 3. Question 4: Present your data, including any graphs, in a reasonable fashion. (You need to decide how best to present your data.) Now, my total data set is in the Excel spreadsheet accompanying this report, but the results are as follows: Quantity NOT DISTRACTED DISTRACTED Average reaction time (s) 0.14 ± 0.01 0.22 ± 0.01 Average distance the ruler fell (m) 0.1 ± 0.01 0.26 ± 0.02 Standard error in time (s) 0.0079 0.010 Error due to sys and si (s) 0.002 0.001 Jake Mokris (with Ji Kim) Group 0 September 18, 2011 So, when I distracted myself, my reaction time increased over 50%. Also, my error due to systematics and the smallest increment of my ruler is much smaller than my standard error in time, so my values for error are reasonable. By rough estimate, I could perform at least one hundred trials...
