Based on the frequency polygon displayed below, the most common test grade was around what score? Explain. In a box plot, what percent of the scores are between the lower and upper hinges? For the data from the 1977 Stat. and Biom. 200 class for eye color, construct: pie graph horizontal bar graph vertical bar graph a frequency table with the relative frequency of each eye color Eye Color Number of students Brown 11 Blue 10 Green 4 Gray 1 (Question submitted by J. Warren, UNH) 4. A graph appears below showing the number of adults and children who prefer each type of soda. There were 130 adults and kids surveyed. Discuss some ways in which the graph below could be improved. 5. Which of the box plots below has a large positive skew? Which has a large negative skew? (relevant section & relevant section)

Question One
A frequency polygon is a statistical graph that shows data and their respective frequency.
Normally, data points are plotted on the horizontal axis and the respective frequency of the data
point is plotted on the vertical axis. The peak of the plot represents the data point with the
highest frequency. (Lane 2017). In this question, the peak of the plot corresponds to 85 score on
the x-axis. Thus 85 score was the most common grade.
Question Two
Statistically, the percentage of data points that are contained by the lower and the upper
quartiles of a box plot is considered to be 50%. The lower quartile is at the 25th percentile while
the upper quartile (upper hinge) is at the 75th percentile. A correctly constructed box plot clearly
shows the distribution of the data and other crucial aspects of the data at hand.
