Front

How do you read a dot plot?

Back

To read a dot plot, count the number of dots above each value on the number line to determine the frequency of each data point.

What does the term 'outlier' mean in data?

Back

An outlier is a data point that differs significantly from other observations in a dataset.

Front

How do you find the range of a dataset?

Back

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

Front

What is the purpose of a dot plot?

Back

The purpose of a dot plot is to provide a visual representation of data distribution and frequency.

Front

How can you identify the mode in a dot plot?

Back

The mode is identified as the value with the highest number of dots above it in the dot plot.

Front

What does it mean if a dot plot is skewed?

Back

A skewed dot plot indicates that the data is not symmetrically distributed, with more values on one side.

Front

How do you determine the frequency of a specific value in a dot plot?

Back

Count the number of dots that are placed above that specific value on the number line.

Front

What is a frequency distribution?

Back

A frequency distribution is a summary of how often each value occurs in a dataset.

Front

How can you tell if a dataset has a high variability?

Back

High variability in a dataset is indicated by a wide spread of dots in a dot plot.
