Data Analysis
c. Graph showing the mean IQ Score by gender
Box plot compares the median, and quartiles (first and third). From the boxplot, it’s clear that
median of IQ Score of males is higher than that of females. Also, the interquartile range of the IQ
Score of males is bigger due to the elongated box than that of Female. This implies that there’s
great dispersion of IQ Score in males than in females.
