Types of Distributions

Front

What is a right-skewed distribution?

Back

A right-skewed distribution is one where the tail on the right side is longer or fatter than the left side. Most of the data points are concentrated on the left, with fewer high values on the right.

What is a symmetrical distribution?

Back

A symmetrical 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.

How can you identify a right-skewed distribution in a histogram?

Back

In a histogram, a right-skewed distribution will show a concentration of data on the left side with a tail extending to the right.

What is the mode of a distribution?

Back

The mode is the value that appears most frequently in a data set. In a distribution, it can indicate the peak of the graph.

What is the median of a distribution?
