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.

Front

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.

What is a left-skewed distribution?

Back

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

Front

What does it mean for a distribution to be uniform?

Back

A uniform distribution is one where all outcomes are equally likely. The graph of a uniform distribution is a rectangle, indicating that each value has the same frequency.

Front

What is a bimodal distribution?

Back

A bimodal distribution is one that has two different modes or peaks. This indicates that there are two different groups within the data.

Front

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.

Back

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

Front

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.

Front

What is the mean of a distribution?

Back

The mean is the average of all data points in a distribution, calculated by summing all values and dividing by the number of values.

Front

What is the median of a distribution?

Back

The median is the middle value of a data set when it is ordered from least to greatest. It divides the data into two equal halves.
