Distribution of Section 2 Scores Relative Frequency 0.3 0.25 0.2 0.15 0.1 0.05 50 60 70 80 90 Score O a. Section 2 had a higher standard deviation on the exam since the distribution is symmetric. O b. Section 2 had a higher standard deviation on the exam since there are more scores on the low end and more scores on the high end of the distribution. O G. Section 1 had a higher standard deviation on the exam since the distribution is more skewed. O d. Section 1 had a higher standard deviation on the exam since there are more scores on the low end and more scores on the high end of the distribution.
