This is not of normal distribution as 95% of the data is not within 2 s.d either side of the mean. I can conclude that my hypothesis has been proven, and that Girls between 11 and 16 at Withington Girls School DO have faster reaction times in the morning than in the afternoon. As a small extension, I decided to test three other girls outside our school aged between 11 and 16. This will show whether the data I collected was representative of the entire population of girls aged 11-16. I predict that the results should be around the same as which school you attend should not affect whether or not your reaction times are quicker in the morning than in the afternoon. The results were as follows.. Median Time for Each Pupil Year Pupil Dominant AM Non Dominant AM Dominant PM Non Dominant PM 8 1 13 16 15 18 10 2 14.5 19 17 23 11 3 6 8 6.5 9 These results show that girls aged 11-16 have quicker reaction times in the morning than in the afternoon. However, to really prove this, I would need to take reaction times from many more girls aged 11-16 across the country. If I had had more time, I would have looked into whether or not the same hypothesis could be proved in males aged 11-16. I would also have seen if age made a difference, for example would people aged 71-76 have slower reaction times than those aged 11-16. I could have looked at all sorts of aspects (age, gender, environment etc) and seen how these altered reaction times. The variables I listed at the beginning could have been altered to see how this affected reaction times. I might also have taken certain measures to ensure my data was more accurate. For example I could have * taken a larger sample size- in a larger sample, trends would have been easier to identify * made the participants repeat the experiment more than 5 times for each dominant and non dominant in am and pm. * used a computerized device to measure the reaction times- results such as it taking some participants 0 hundredths of a second are clearly not possible and therefore inaccurate, showing how easy it is for human error to take place
