Shapes of Distributions

Front

What is a skewed left distribution?

Back

A distribution where the tail on the left side is longer or fatter than the right side, indicating that most data points are concentrated on the right.

Front

What is a skewed right distribution?

Back

A distribution where the tail on the right side is longer or fatter than the left side, indicating that most data points are concentrated on the left.

Front

What does a symmetrical distribution look like?

Back

A distribution where the left and right sides are mirror images of each other, indicating that data points are evenly distributed around the mean.

Front

What is a uniform distribution?

Back

A distribution where all outcomes are equally likely, resulting in a flat shape when graphed.

Front

What is bimodal distribution?

Back

A distribution with two different modes or peaks, indicating that there are two prevalent values in the data set.

Front

What is the mean in a skewed left distribution?

Back

The mean is typically less than the median due to the influence of lower values.

Front

What is the mean in a skewed right distribution?

Back

The mean is typically greater than the median due to the influence of higher values.

Front

What is the median in a symmetrical distribution?

Back

The median is equal to the mean, as the data is evenly distributed.
