What does it mean if a distribution is skewed left?

Back

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

Front

What are the characteristics of a skewed left distribution?

Back

In a skewed left distribution, the mean is less than the median, and the graph has a longer tail on the left.

Front

What are the characteristics of a skewed right distribution?

Back

In a skewed right distribution, the mean is greater than the median, and the graph has a longer tail on the right.

Front

What is the mean in a symmetrical distribution?

Back

In a symmetrical distribution, the mean is located at the center of the distribution.

Front

What is the median in a skewed left distribution?

Back

In a skewed left distribution, the median is greater than the mean.
