Range Flashcards

The difference between the highest and lowest values in a data set.

Subtract the smallest value from the largest value in the data set.

For the data set {3, 7, 10, 15}, the range is 15 - 3 = 12.

Outliers can significantly affect the range, as it depends on the extreme values.

For grouped data, the range is calculated as the difference between the highest and lowest class boundaries.

The range measures the total spread of data, while the interquartile range measures the spread of the middle 50% of the data.

The range can be used to compare the spread of two or more data sets.

In real-life problems, the range can indicate variability, such as temperature differences or test score spreads.

The range can be estimated from a cumulative frequency graph by finding the difference between the highest and lowest values.

The range does not consider how data is distributed and is sensitive to extreme values.
