Aziz wonders how many pieces of pizza people tend to eat at a pizza party. He surveys 11 people at the end of a pizza party and asks them how many pieces of pizza they ate. A list of his result follows. Find and interpret the mode of his data. Number of pizza eaten: 6, 2, 1, 2, 4, 5, 2, 2, 4, 6, 7.
The mode is the number that appears most frequently in a set of data. In this case, the number 2 appears most frequently, as it is mentioned three times in the list:
2, 2, 2
Therefore, the mode of Aziz's data is 2. This means that most people at the pizza party ate 2 pieces of pizza.
