Shapes of Distributions

Front

What is the shape of a distribution that is symmetrical?

Back

A symmetrical distribution has a mirror-like quality where the left and right sides are approximately equal. An example is the normal distribution.

Front

What does it mean for a distribution to be skewed left?

Back

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

Front

What does it mean for a distribution to be skewed right?

Back

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

Front

What is a uniform distribution?

Back

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

Front

What is an example of a symmetrical distribution?

Back

The normal distribution is a common example of a symmetrical distribution.

Front

How can you identify a skewed right distribution?

Back

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

Front

How can you identify a skewed left distribution?

Back

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

Front

What is the relationship between mean, median, and mode in a symmetrical distribution?

Back

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

Front

What is the mode of a distribution?

Back

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

Front

What is the median of a distribution?

Back

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