Explanation Calculation: Answers may vary. One of the possible answers is given below: The data relates to the amount of money spent by the males and females in the Georgia Student Survey. Here, “0” denotes males and “1” denotes females. In order to compare the players, the graphical and numerical methods used are: • Box plots of the amounts spent. • Histogram of the distribution. • Descriptive statistics of scores: mean, standard deviation, sum, minimum, first quartile , median , third quartile, maximum, range , interquartile range and mode . Boxplot: Software procedure: Step-by-step procedure to obtain the boxplot using the MINITAB software: • Choose Graph > Boxplot > With groups . • Under Graph variables , enter the columns of Haircut . • Under Categorical variables for grouping , enter the column of Gender . • Click OK in all dialog boxes. Output using the MINITAB software is given below: Interpretation: The boxplots show that for males (0), the spread of the data is very less. The line inside the boxplot is towards the higher bound of the box, indicating a left-skewed distribution. For females (1), the boxplot shows a much greater spread. The line inside the box, that is, the median is closer to the lower end of the box. Moreover, the higher whisker is also longer, indicating a right-skewed distribution. There are two points, marked by asterisks, which are unusually high, marking outliers. Henceforth, enter the data related to males and females in two separate columns, “Haircut_Male” for males and “Haircut_Female” for females. Histogram: Software procedure: Step-by-step procedure to obtain the histogram using the MINITAB software: • Choose Graph > Histogram > Simple . • Under Graph variables , enter the columns of Haircut_Male, Haircut_Female ...
