half the students in a class scored 80% on an exam, most of the rest scored 85% except for one student who scored 10%. What is the best measure of central tendency for the test scores?

Solution

lets say there are total 10 students

half of them scored 80%

that is 5 students scored 80%

4 scored 85% and 1 scored 10%

so, mode = 80% since maximum scored 80%

mean = (80+80+80+80+80+85+85+85+85+10)/10 = 75

median = 80+80 / 2 = 80

hence , mode and median have same values , so either median or mode is best measure of central tendency
