Very good consensus	Median and middle 50% (interquartile range) of respondents are found at 1 integer (eg, median and interquartile range are both at 8) or 80% of respondents are within 1 integer of the median (eg, median is 8, 80% respondents are from 7 to 9)
Good consensus	50% of respondents are within 1 integer of the median (eg, median is 8, 50% of respondents are from 7 to 9) or 80% of the respondents are within 2 integers of the median (eg, median is 7, 80% of respondents are from 5 to 9)
Some consensus	50% or respondents are within 2 integers of the median (eg, median is 7, 50% of respondents are from 5 to 9) or 80% of respondents are within 3 integers of the median (eg, median is 6, 80% of respondents are from 3 to 9)
