How can you identify low variation in a histogram?

Back

Low variation is identified in a histogram by a narrow shape, where most data points cluster around a central value.

Front

How can you identify high variation in a histogram?

Back

High variation is identified in a histogram by a wide shape, where data points are spread out over a larger range of values.

Front

What is the purpose of using bins in a histogram?

Back

Bins are used in a histogram to group data points into ranges, making it easier to visualize the distribution.
