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. His results follow. Find and interpret the median of his data. Number of pieces of pizza eaten: 6, 2, 1, 2, 4, 5, 2, 2, 4, 6, 7.
To find the median of the data, we first need to arrange the numbers in ascending order:
1, 2, 2, 2, 4, 4, 5, 6, 6, 7
Since there are 11 numbers, the middle number would be the 6th number when arranged in ascending order. In this case, the 6th number is 4.
Therefore, the median number of pieces of pizza eaten at the pizza party is 4. This means that half of the people surveyed ate 4 pieces of pizza or fewer, and half ate 4 pieces of pizza or more.
