Shape of a Graph - Dot Plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of data points plotted on a simple scale, often using dots to represent individual data points.

Front

What does it mean if a distribution is uniform?

Back

A uniform distribution means that all outcomes are equally likely; the data points are spread evenly across the range.

Front

What does it mean if a distribution is skewed?

Back

A skewed distribution is one where the data points are not symmetrically distributed; one tail is longer or fatter than the other.

Front

What is a bell-shaped distribution?

Back

A bell-shaped distribution, also known as a normal distribution, is symmetrical and has most of the data points concentrated around the mean.

Front

What does it mean if data is skewed to the left?

Back

If data is skewed to the left, it means that the left tail of the distribution is longer or fatter, indicating that there are more lower values.

Front

What does it mean if data is skewed to the right?

Back

If data is skewed to the right, it means that the right tail of the distribution is longer or fatter, indicating that there are more higher values.

Front

How do you find the range of a data set?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

What is a symmetrical distribution?

Back

A symmetrical distribution is one where the left and right sides of the graph are mirror images of each other.

Front

What is the mode of a data set?

Back

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

Front

What is the median of a data set?

Back

The median is the middle value when the data points are arranged in ascending order.
