The difference between the largest and smallest measurements in a data set is called the

• A. Range
• B. Variance
• C. Standard Deviation
• D. IQR

Answer: (A)

Range measures how spread out a data set is by looking at the distance between its largest and smallest values. It’s computed as max minus min, so it gives a quick, intuitive sense of overall variability. But because it relies only on the extreme values, it can be heavily affected by outliers. Other measures, like variance and standard deviation, take into account all data points and describe typical deviation from the mean, while the interquartile range focuses on the middle 50% of the data to resist outliers. Since the question describes the difference between the largest and smallest measurements, the appropriate term is range.
