The averages for each music type will be calculated to see the results of the experiment. ]]> 2018-04-13 15:04:27 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/251593051 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/251594135 Because every subject is driving to each type of music, they will drive the course four times. They could end up learning the course and getting better, and therefore swaying the results. People could also be biased in the type of music they enjoy listening to. If they enjoy a certain type of genre it could sway the results because it could measure enjoyment instead of focus. ]]> 2018-04-13 15:06:31 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/251594135 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/251620344 Does the type of music affect ones driving ability?]]> 2018-04-13 15:58:42 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/251620344 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/251620875 48 people will be taken from an online ad to participate in the study. It will be volunteer based, but participants are promised money for participation. These people will be random and of all different ages/genders/ driving backgrounds. ]]> 2018-04-13 15:59:49 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/251620875 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/251621894 We will receive inquiries from an online ad of people who want to participate. They will be given numbers 01- however sign up and then placed in a random number generator to conduct a SRS.

The volunteers driving will be going around a set up corse that will vary with every genre of music so they do not memorize the corse. ]]> 2018-04-17 14:41:24 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252599736 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252602489 We will replicate this experiment with a new group of volunteers to show that our results are valid and reliable. ]]> 2018-04-17 14:46:24 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252602489 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252603580 Out of the 48 people who volunteered we split them up by gender and age. This was to separate by skill and experience level and also the gender bias that is put on women drivers.]]> 2018-04-17 14:48:39 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252603580 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252608024 Our subjects will be getting into the car not knowing the corse that is set up for each turn. Each time they enter a car they will also not know what genre of music they will be given. It will be a double blind because the instructor in the car with them will not know what the subject is given as well.

This will be a good size sample group because our margin of error is so low. This shows that our experiment should be a good representation of the population of drivers. ]]> 2018-04-17 15:01:47 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252610650 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252614216 We randomized all 48 people and the results of the randomized difference was 3 seconds, and the actual difference between results was an average of 4 seconds, so it is not statistically significant because it could randomly have a difference of 4 seconds. ]]> 2018-04-17 15:08:00 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252614216 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252614614 Our results were published and sent to all dealers to get data on the correlation between car’s audio systems and a drivers focus. They could invent new safety features to lower audio sound for drivers driving at high speeds. This data could be very valuable in the automotive safety community because it could tell them what causes drivers to drive certain ways. ]]> 2018-04-17 15:08:46 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252614614 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252640223 At the end of all of the tests, the average time for people to complete the course for the control group was 1:43 seconds. The average time for the country music genre group was slightly higher at 1:51 seconds, and the rap genre group was much higher at 2:03 seconds. The metal genre had the longest average time at 2:15. This data shows that no music, or our control group, was the most focused drivers and therefore, they were able to get the best average time compared to the other genres. ]]> 2018-04-17 15:54:42 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252640223 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252643191 Each participant was promised $100 for their participation in the study. We paid put $4800 to the volunteers to do the study, and also had to rent out 4 cars and space for a track which cost the company $5000. It was a relatively expensive experiment at $9800. There were hidden expensis in the experiment with renting space, cars, and paying for equipment. ]]> 2018-04-17 16:00:15 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252643191 paigeslezakk https://padlet.com/paigeslezakk/Headbanginrides/wish/252647187 Our treatment group will test drive each car for each genre including the control car. Because they will be trying each treatment, it is a crossover design. This will make our data more reliable because we will have more data with less people. ]]> 2018-04-17 16:08:04 UTC https://padlet.com/paigeslezakk/Headbanginrides/wish/252647187
