About what percent of the data in a data set falls between the first quartile and the median value​? Explain.

Answer 1

Approximately 25% of the data in a data set falls between the first quartile and the median value. This is because the first quartile represents the 25th percentile of the data set, while the median represents the 50th percentile. Therefore, the difference between the first quartile and the median represents the middle 25% of the data set.
