Shapes of Distributions

Front

What is a skewed distribution?

Back

A skewed distribution is one where the data points are not symmetrically distributed around the mean, resulting in a tail on one side.

Front

Which measure of central tendency is most appropriate for skewed distributions?

Back

Median is the most appropriate measure of central tendency for skewed distributions because it is not affected by extreme values.

What does it mean if a distribution is right skewed?

Back

A right skewed distribution has a longer tail on the right side, indicating that the majority of data points are concentrated on the left.

Front

What is a bimodal distribution?

Back

A bimodal distribution has two different modes or peaks, indicating that there are two prevalent values in the dataset.

Front

What is a unimodal distribution?

Back

A unimodal distribution has one clear peak or mode, indicating that there is one prevalent value in the dataset.

Front

What is a symmetric distribution?

Back

A symmetric distribution is one where the left and right sides of the distribution are mirror images of each other.

Front

What is a uniform distribution?

Back

A uniform distribution is one where all outcomes are equally likely, resulting in a flat histogram.

How can you identify a left skewed histogram?

Back

A left skewed histogram will have a longer tail on the left side and the bulk of the data will be on the right.
