This paper reports comparing the Age of My Morning Students and the hypothetical data, Age of My Evening Students obtained from random data generation. From the steam-and-leaf plots below, it is observed that the Age of my Morning Students has two outliers of 41 and 45 years while Age of my Evening Students has no outlier.

Figure 2
From the Steam-and-leaf, above, it is observed that the medium age for the morning class group lies between 22-23, with the ages below the number of students whose ages are more significant than the medium steam being greater than those with ages above the medium group. Unlike the morning class, the evening class's ages are observed to be evenly distributed with the medium value between 34 and 35.
Similar outliers (extreme ages) values in the classes are observed in the Box plot shown in figure (3). From the box plot, it is also observed that the average age for the evening class is greater than that of evening student (M=24, SD=1.31) compared (M=33.55, SD=1.79) as observed in the Minitab descriptive statistics shown in figure (5)

Figure 5: Descriptive Statistics
From the five-number summary shown in figure (6), it is observed that the minimum and maximum ages for the two groups of students are the same. However, the age of my Morning Students has lesser lower quartile, median and upper quartile. Relative to the minimum and maximum ages in morning and evening classes, it observed that the medium of the latter variable is centrally placed indicating that this data has a normal distribution relative to the former that appears to be skewed to the left both as shown by stem-and-leaf diagram and the 5-number summary.
