What is the range of the data set 5, 7, 9, 11, 50?

Answer and explanation

Answer: H: 45

The range is the maximum minus the minimum: 50−5=4550-5=45, choice H. The large value 5050 stretches the range, because it is far from the other four values, which lie between 55 and 1111. Choice J (5050) is the maximum value alone. Choice F (66) is the range of the first four values, 11−511-5. Choice G (99) is the median. The range measures the whole spread of the data, so it is sensitive to outliers like 5050.
