Question

BlackTom AI · Accepted Answer

In this question, the concept being described is the range defined as the difference between the first quartile (Q1) and the third quartile (Q3). This specific range is commonly known as the interquartile range (IQR).

Option context: The prompt indicates the expected answer should be a single word or a single number, in lowercase. When expressing the term in one word, 'interquartile' is a plausible single-word form derived from the full term 'interquartile range.' An alternative accepted shorthand in statistics is 'iqr' (lowercase), but the provided answer example uses 'interquartile.'

Why this matches the concept: The interquartile range measures the spread of the middle 50% of the data, computed as Q3 minus Q1. It is unaffected by extreme outliers and is a robust measure of variability.

Why other possibilities (if any) might be incorrect: If there were choices like 'range' or 'variance,' those refer to different concepts. The simple 'range' typically denotes the difference between the maximum and minimum values, not the spread of the middle half of the data. 'Variance' or 'standard deviation' describe dispersion around the mean, not the quartile-based spread. If the instruction demands a single word in lowercase, ensuring the form aligns with that constraint means selecting a term that compactly conveys the same idea, such as 'interquartile' or 'iqr,' rather than the full two-word phrase 'interquartile range.'
