Kaylen wants to know the number of siblings 6th graders typically have. She surveys the 6th graders on her soccer team. Her results are given in the table. She calculates that the median number of siblings is 1. She then realizes that she counted one data value twice by accident. She needs to remove one of the “0 siblings” values from the table. Determine how removing a “0” from the dataset will impact the median.

Answer 1

Original total = 23, median is the 12th value = 1.
After removing one 0, total = 22, median is average of the 11th and 12th values. Both of those are still 1, so the new median = 1.

Answer: The new median is 1. The median stayed the same.
