Shapes of Distributions

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. The mean, median, and mode are all equal.

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. Most of the data points are concentrated on the right, and the mean is less than the median.

Back

A right-skewed distribution has a longer tail on the right side. Most of the data points are concentrated on the left, and the mean is greater than the median.

What is the mean in a distribution?

Back

What is the median in a distribution?

How can you identify a skewed left distribution visually?

Back

In a skewed left distribution, the bulk of the data points are on the right side, with a tail extending to the left.

Front

How can you identify a skewed right distribution visually?

Back

In a skewed right distribution, the bulk of the data points are on the left side, with a tail extending to the right.

Front

What is a normal distribution?

Back

A normal distribution is a symmetric, bell-shaped distribution where most of the data points cluster around the mean.

Front

What is the range in a distribution?

Back

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