Document Summary
Page 1 of 3: the following are the salaries of employees in a small business: Yes my answer in part a was correct: find the standard deviation and the iqr of the data. The interquartile range is 10,000: describe the shape of the distribution terms of its overall shape, clusters gaps, or outliers, and skewness. The data set is skewed to the right. There is a gap from the values 29,000 to the value 45,000. There are clusters near the 15,000 to 23,750 data set, and clusters from the 25,000 to the 29,000 data set too. If you were to plot the data on a histogram it would be skewed right: speculate on the reasons for why the distribution is shaped as it is. The mean is greater than the median in this data set: the graph below shows a box plot of the data superimposed over the histogram.
