What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted on a number line, representing the frequency of data points.

Front

How do you identify the highest score in a dot plot?

Back

The highest score is represented by the rightmost dot or the highest stack of dots on the plot.

Front

What does an outlier represent in a data set?

Back

An outlier is a data point that differs significantly from other observations, often indicating variability in the data.

Front

How can you find the total number of students represented in a dot plot?

Back

Count the total number of dots or the height of each stack of dots to find the total number of students.

Front

What does it mean if there are no outliers in a data set?

Back

It means that all data points are within a similar range and there are no extreme values that differ significantly from the rest.

Front

How do you determine how many students scored below a certain percentage in a dot plot?

Back

Count the number of dots or stacks of dots that fall below the specified percentage on the plot.

Front

What is the purpose of using a dot plot?

Dot plots are used to visualize the distribution of data points, making it easy to see patterns, trends, and outliers.

Front

How can you visually identify an outlier in a dot plot?

Back

An outlier can be visually identified as a dot that is isolated from the rest of the data points, often far away from the main cluster.

Front

What does the height of a stack of dots represent in a dot plot?

Back

The height of a stack of dots represents the frequency or number of occurrences of that particular value.

Front

What is the significance of the x-axis in a dot plot?

Back

The x-axis represents the values of the data points, allowing for comparison of frequencies across different values.
