How does Noise affect Coordination

For my science fair project, I decided to do it on "How does Noise Affect Coordination" and I extended that question by seeing if there is a difference between girls, boys, and adults because genders and age may affect how well people coordinate things and how loud noises and quiet noises can affect them. I decided to do this project because I thought it was original and unique, and I felt that my results could be applied to the world because people will know the best place to do coordination activities for their specific gender and age.

For my experiment, my noise environments were a silent room (0 dB), in a room with someone tapping their pencil on a table (about 20 dB), in a room with an alarm clock ringing (about 80 dB), and the school hallway at lunch (95-100 dB) and my coordination activities were threading a needle through a hole and throwing a quarter into a cup 5 times.

For my procedure, I gathered 30 test subjects, 10 were girls, 10 were boys, and 10 were adults. One by one, I would have each of the test subjects thread a needle and throw the quarter into the cup in the noise environments. When they were doing the experiment, I would time them and I would record the time down in a chart. I would have the test subjects throw the quarter into the cup twice, meaning that they will throw the coin into the cup five times and then they would do it again to make sure that it wasn't a lucky throw. When I finished my experiment, I did it for the second time to confirm my results and to see if there was any significant change in my results.

When I finished the experiment, the results actually surprised me. All the test subjects took the shortest amount of time threading a needle and throwing a coin into a cup in the silent environment and they took the longest in the school hallway. The shocking part was that the girls took longer threading a needle and throwing a coin into a cup with the pen tapping than the alarm clock room but the boys took longer in the alarm clock room than the pen tapping room.

For my conclusion, I found out that part of my results agreed with my hypothesis but part of my results proved my hypothesis wrong. My hypothesis was "If the noise is louder and less common, then the person will take a longer amount of time coordinating the target." So I was predicting that the girls and boys will take the shortest amount of time doing the two coordination activities in the silent room, then the room with the pen tapping, third will be the alarm clock room , and they will take the longest amount of time in the school hallway and as you can see my prediction about the boys were right but the girls proved me wrong.
