Question

When might the inter-quartile range be better for describing a data set than the range?

Answer 1

I think the answer is C. if the data has outliers

if the data has outliers it means that it has extreme values

, for example 1, 4000, 4500,  5000, 5500, 6000,  10000000000

1 and 10000000000 are considered as the outlier, which is not fair to be used as a range of measure

Hope this helps

Answer 2

When might the inter-quartile range be better for describing a data set than the range?

Answer: First we have to understand that a interquartile is the distance between the first and third quartiles of a data set. It is the upper quartile minus lower quartile. Out of all the options shown above the one that represents when it might be better to use for describing a data set than the range is answer choice C) if the data has outliers.

I hope it helps, Regards.
