Range Flashcards

All 6 cards in this deck

What is the range of a set of data?

Largest value $-$ smallest value.

What does the range measure?

The spread of the data, not an average.

True or false? The range is written as two numbers, e.g. "12 to 22".

False. The range is a single number found by subtracting: $22-12=10$.

What is an outlier?

A value that is much larger or much smaller than the rest of the data.

What effect does an outlier have on the range?

It makes the range much larger, so the range no longer represents the typical spread.

True or false? A smaller range means the data are more consistent.

True. Less spread means the values are closer together.
