The mean or average for all the worksites within Sun Coast is 124.83dB. The median or middle number for all noise levels is 125.72dB and the most common level of noise is 127.31dB.
UNIT VII SCHOLARLY ACTIVITY 26 Evaluation. There are many variables that determine how much dB an employee will be exposed to in the workplace. These variables can change at anytime and so could the location of the employee. In my opinion, the assumption for parametric statistical data cannot be met because of these many variables. However, if the mean is used for all workplaces, then it can be assumed that all employees will need the best hearing protection as it is over the 120dB range.

In my opinion, the measurement scale to use to compare training scores between an updated training course and an original training course would be interval. This method allows data to be compared to show an improvement or deficit in the new training program. Measure of central tendency. The average or mean of the test scores shows an improvement in the new training program. The mean for the original test score was a score of 69 while the mean for the new training was an 84. The median score for the original training program was a 75 while median

According to the descriptive statistics above, it can be assumed that the new training program is more effective than the original training program if you are looking at it from a statistical standpoint. In my opinion, the assumptions for parametric statistical testing were met because the trends do show better test scores with a newer training session with the data provided.
