The statistic is interquartile range.

Interquartile range is a measure of dispersion that is calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3). To calculate the interquartile range for the 10 dental practices, the insurance company first needs to organize the cash (non-insurance) prices for the procedure at each practice in ascending order. The lower quartile (Q1) is the median of the first 5 values and the upper quartile (Q3) is the median of the last 5 values. The interquartile range is then calculated by subtracting the lower quartile (Q1) from the upper quartile (Q3). In this case, the interquartile range is $74

The interquartile range is the range of values between the 25th and 75th percentiles. In this case, the statistic is the interquartile range for the cash price for filling a cavity across 10 dental practices in California. The interquartile range is $74, meaning that the price for filling a cavity at the 25th percentile is $74 lower than the price at the 75th percentile.
