Determine the Mode of a Variable from Raw Data
-The accompanying data set contains quiz scores for 12 students in a chemistry class: $$18,15,5,8,15,20,2,16,10 \text {, }$$ $$12,20,15$$ a. Find a measure of central tendency that separates the data into two groups such that each group consists of 50% of the scores above and 50% of the scores below that measure. b. Find a measure of central tendency that represents the quiz score that occurs most often. c. Find a measure of central tendency that represents the average of the 12 quiz scores.
