The Shapes of Distributions

Front

What is a left-skewed distribution?

Back

A left-skewed distribution, or negatively skewed distribution, has a longer tail on the left side. Most data points are concentrated on the right, with fewer low values.

Front

What is a right-skewed distribution?

Back

A right-skewed distribution, or positively skewed distribution, has a longer tail on the right side. Most data points are concentrated on the left, with fewer high values.

Front

What does a uniform distribution look like?

Back

A uniform distribution has all outcomes equally likely, resulting in a flat shape. The frequency of each value is approximately the same.

Front

What is a symmetrical distribution?

Back

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

Front

What is the mean in a symmetrical distribution?

Back

In a symmetrical distribution, the mean, median, and mode are all equal.

Front

How can you identify a left-skewed distribution on a graph?

Back

In a left-skewed distribution, the peak of the graph is on the right side, and the tail extends to the left.

Front

How can you identify a right-skewed distribution on a graph?

Back

In a right-skewed distribution, the peak of the graph is on the left side, and the tail extends to the right.

Front

What is the mode in a distribution?

Back

The mode is the value that appears most frequently in a data set.

Front

What is the median in a distribution?

Back

The median is the middle value when the data set is ordered from least to greatest.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.
