The range and interquartile range
WebbHowever, it should be noted that in journals and other publications you will usually see the interquartile range reported as 45 to 71, rather than the calculated range. A slight variation on this is the semi-interquartile range, which is half the interquartile range = ½ (Q3 - Q1). Hence, for our 100 students, this would be 26 ÷ 2 = 13. WebbThe range is 6.4. The interquartile range is 0.6. Alternatively, use the formulae to locate the LQ and UQ. The LQ is the value; LQ = 3.1. The UQ is the value; UQ = 3.7. b) Give a reason why, in this case, the interquartile range may be a better measure of how spread out the data is than the range.
