gender of a person affects their ability to hear

Analysis

From the results you can see that the males have a slight tendency to hear better, however the results do not show a considerable difference in the hearing ability between the genders so a further experiment would be necessary to further confirm or disprove the results as the results already collected could have been susceptible to errors. These errors in the results could have been caused by the conditions the experiment took place in; on the day there was some bad weather as well as strong wind which may well have traveled the sound waves from the whistle, thus affecting the ability to hear the sounds from the air. Another condition that was not kept the same and could have affected the results we collected was the sound produced from the sound of the whistle. Since the whistle can produce a variety of different volumes depending on how hard it is blown this may perhaps have caused a quieter or louder sound to be produced which would have affected the results.

To improve this experiment it would be necessary that we carry it out on a clear day with little wind, and use a sound that could easily be kept constant such as a pre-recorded sound.
