The concept of average is important when analyzing large sets of data. For example: a) What is the most common height in your class? b) Who is taller on average, girls or boys, in your classroom? c) If you arrange your classmates in order of increasing height, how tall is the person in the middle? All these questions require the consideration of average values. However, each of these questions asks a different kind of average. What is the correct matching between the questions and the type of average?
