The standard deviation of the sample is 38.10; this shows that the data isnot widely distributed [ CITATION Tro062 \l 1033 ]. Further, looking at the kurtosis and skewnesswe can conclude that the data is approximately normal.There are no outliers in the sample data for the variable “Salary”. This can be confirmed from theboxplot provided below.

Minority ofparticipants (1%, n = 1) were less than or equal to 3 years old at the university Table 2: Length of stayLength of stayFrequencyPercent≤ 3 years11%> 3 years and ≤ 6 years4545%> 6 years and ≤ 10 years2525%
