Question: what is the relationship between quartiles and?
Answer: Quartiles and Interquartile Range Quartiles tell us about the spread of a data set by breaking the data set into quarters, just like the median breaks it in half. ... This means that when we calculate the quartiles, we take the sum of the two scores around each quartile and then half them (hence Q1= (45 + 45) ÷ 2 = 45) .
