Common mistake
Confusing Range and Inter-Quartile Range
Students often confuse the range with the inter-quartile range, thinking they are the same measure of spread.
Remember that the range is the difference between the highest and lowest values, while the inter-quartile range is the difference between the first and third quartiles, representing the middle 50% of the data.
