The correct response is C- The range is still 6, but the interquartile range is now 3.5. The range stayed the same, but the interquartile range changed slightly.
Adding a "3" to the dataset does not impact the range as it is determined by the difference between the highest and lowest values, which remains the same at 6. However, adding a "3" to the dataset does impact the interquartile range, as it is determined by the difference between the upper quartile and lower quartile. When "3" is added to the dataset, the median changes from 3 to 3.5, causing the interquartile range to change from 4 to 3.5.
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 results follows. Aziz uses his results to calculate that the range for number of pieces of pizza eaten is 6, and the interquartile range is 4. Number of Pieces of Pizza Eaten: 6, 2, 1, 2, 4, 5, 2, 2, 4, 6, 7 After calculating the range and the interquartile range, Aziz realizes he forgot to include himself! He ate 3 pieces of pizza. Determine the range and interquartile range after a “3” is added to the dataset. Describe how adding a “3” to the dataset impacts the range and the interquartile range.
