The mean is the sum of the scores divided by the amount of scores.  Thus, the mean is (82+64+73+91+85)/5, or 395/5, or 79.

mean is the average

basically you add the scores together then divided the sum by the number of quizzes she had so

82+64+73+91+85=sum=395

then divide by number of quizes
there are 5 scores so 5 quizes
395/5=79

the mean is 79
