When the version A Quiz on Module 3 closed in Stat1000Q in Fall of 2020, 135 students were enrolled in the class.
Here is the descriptive statistics of the 135 scores:
Statistics
Variable Total Count Mean StDev Minimum Q1 Median Q3 Maximum
C1 135 6.333 3.122 0.000 4.000 7.000 9.000 10.000
Out of the 135 students, 10 did not take the quiz and (notionally) received a score of 0. No one from among the 125 remaining students (who actually took the quiz) scored 0.
Clearly, the mean score of 6.333 does not properly reflect the performance of the students who took the quiz.
Find the mean score of the 125 students who actually took the quiz. Remember that the score of any one of these 125 students is a whole number between 1 and 10.
Find the standard deviation of the scores of the 125 students who actually took the quiz. Remember that the score of any one of these 125 students is a whole number between 1 and 10.
