Joshua Lucchesi posted May 2, 2017 6:16 PMFor this discussion I researched the salary of nutritionists.I rounded each amount to the nearesttenth.Bureau of Labor Statistics:$58.9ksalary.com:$58.4kpayscale.com:$29.3k / $74.0kmoney.usnews.com:$35.2k / $81kindeed.com:$60.7kallp.com:$69.6kallalliedhealthschools.com:$55.3kowlguru.com:$58.6kMean:(29.3+35.2+55.3+58.4+58.6+58.9+60.7+69.6+74.0+81.0) / 10= 581 / 10= $58.1kMedian:29.3,35.2,55.3,58.4,[58.6,58.9],60.7,69.6,74,81(58.6+58.9) / 2117.5 / 2= $58.8k
The better measure of central tendency is the median salary of $58.8k a year.The median showsan increase amount compared to the mean salary of $58.1k a year.Hi Joshua, you have worked well on this problem with a little mistake. While adding the salaryof nutritionists you have used two salaries from payscale.com and money.usnews.com whichleads to the incorrect value of the actual mean and median. There are three ways to deal with thissituation, first is to take the smallest value, second depend on the belief if you believe that thelargest value seems more appropriate in comparison with others take that one and the last onewhich is the best is take average of the two and use them for further calculations.Now suppose that the calculated mean value and median are correct, then you mentioned medianwould be a better measure, here you did a great job because when the value of the mean is lessthat means the data is skewed and in that condition median would be a better measure of centraltendency.Brittany Baisley posted May 2, 2017 9:55 PMWhen calculating the mean and median salaries of a business analyst, I focused more soon gathering information from different cities. Most of the time when salaries arecalculated, it is based on the cost of living in their area. If someone lives in New Yorkthan Dallas, it is more likely for them to receive a higher salary because of their cost ofliving. According to the measures of central tendency, the mean is used for an averageestimate and median is used to find the middle value. Below I calculate the mean andmedian for an entry level business analyst in 10 different cities.Mean66 + 67 + 67 + 63 + 59 + 63 + 64 + 60 + 65 + 66 = 640 / 10 = 64Median59 + 60 + 63 + 63 +64 +65+ 66 + 66 + 67 + 67
