Investigate the spare-time activity hypothesises EssayDrop (d) in cm Frequency Cumulative Frequency 5 will straightaway confide the results from the accumulative absolute frequency table into a cumulative frequency curve for males and females. From both cumulative frequency curves I can take an try median and inter-quartile range for both females and males. It tells me that the females take up a smaller and lower inter-quartile range, of 4 (16 12=4) than the males whom have a wider and higher one of 7 (19 12= 7).This suggests that the male results in general were to a greater extent varied than those of the females. It also suggests that the approximate median average for females was 14. Whereas the approximate median for males is 15. 5, which implies that the females have a lower response time on median average than males. However, on that point is only a slight leaving. To show the inter-quartile ranges and the median more easyly I have put the information from the cumulative frequency graph into a box plot for each of males and females. These box plots gear up the varied results of the males and the closeness between the females results.I will now use histograms to show the continuous sort data. . Drop (d) in cm Frequency width Frequency Frequency Density 5The standard expiration measures the spread of the data about the wet value.It can allow me to compare males and females, which may have the alike(p) sozzled but a different range. Gender Mean average Step 1From the results of the standard disagreement I can distinguish that the distribution round the mean average of the female and male frequency was very low. The standard deviation suggests that the females results are generally more spread out round the mean rather than the males whom are not so spread out. This means that males generally have similar response times rather than females whom the results imply to have more varied results.Conclusion From the data I self-collected I have found that males appear to have better reaction times than females, which seems to be connect closely to them having lower thump rates. This suggests both my hypotheses to be correct and closely linked to one another. Although, on median average females have been implied to have a lower reaction time. However, the male and female median average are extremely similar so due to the males having a increasingly better mean average seem to generally have better pulse rates and reaction times.This proves that everyone has different reaction times, which can be altered by many different variables such as that as pulse rate. Evaluation I could have tested reaction times in a many more ways and did not have to use just light as a stimuli for the reaction time. I could have used sound like the reaction time for someone to hear the sound of a gun at a beginning of a race and to react to that and start running. Also the subjects results could have been affected by anything from light an d sound distractions to whether they had consumed a substance containing caffeine before they had taken naval division in the activity set for them.Some of these will not have been able to improve on but others such as where and when I had collected my data may have made attainable for bias results to come up in my investigation. Whether the subjects were tired, focussed, motivated will have made a difference to their performance as well so external influences can play a big composition in the alteration of results. Also if the participant had carried out this particular type of investigation before or if they trained specially to improve a reaction like those whom train for sprinting would have had a clear advantage than those whom had not carried out the experiment before.In my experiment I also found that an exact recording of how far the ruler actually dropped before it was caught hard and can be seen to have been move to the nearest centimetre, which will not have not give n me very accurate results.
