Distribution Shapes

What is a Bell Shape distribution?

Back

A Bell Shape distribution, also known as a normal distribution, is a symmetrical distribution where most of the observations cluster around the central peak and probabilities for values further away from the mean taper off equally in both directions.

What does it mean for a distribution to be Bimodal?

Back

A Bimodal distribution has two different modes or peaks in its frequency distribution, indicating that there are two prevalent values in the dataset.

Front

Define a Uniform distribution.

Back

A Uniform distribution is a type of distribution in which all outcomes are equally likely; the graph of a uniform distribution is a rectangle.

Front

What characterizes a Left Skewed distribution?

Back

A Left Skewed distribution, or negatively 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 is a Skewed Right distribution?

Back

A Skewed Right distribution, or positively 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 does Symmetrical distribution mean?

Back

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

Front

How can you identify a Skewed Left distribution in a graph?

Back

In a Skewed Left distribution, the graph will show a longer tail on the left side, with most data points clustered on the right.

Front

How can you identify a Skewed Right distribution in a graph?

Back

In a Skewed Right distribution, the graph will show a longer tail on the right side, with most data points clustered on the left.

Front

What is the significance of the mode in a Bimodal distribution?

Back

The mode in a Bimodal distribution represents the two most frequently occurring values in the dataset, indicating two distinct groups.

Front

What is the difference between a Symmetrical and a Uniform distribution?

Back

A Symmetrical distribution has a peak at the center and tapers off equally, while a Uniform distribution has no peaks and all values are equally likely.
