Question

an elevator can hold a maximum of 1,500 pounds. eight people need to use the elevator. bill had some measures from the data set of how much each person weighed. which measure would be most useful to determine if the people can safely use the elevator? a mean b median c mode d interquartile range

Explanation:

The mean can be affected by extreme values. The mode is the most - frequently occurring value and may not give a good indication of a typical weight. The inter - quartile range measures the spread of the middle 50% of the data and is not relevant for determining the average weight per person. The median represents the middle value when the data is ordered and is less affected by outliers. To determine if people can safely use the elevator, we want to know a value that represents a typical weight. The median is the most useful measure in this case as it gives a central value that is not skewed by extreme weights.

Answer:

B. median
