Clusters, Outliers, Peaks, and Gaps

Front

What is a cluster in a data distribution?

Back

A cluster is a group of data points that are close together in value, indicating a concentration of data in that range.

Front

What does it mean if a graph is symmetrical?

Back

A symmetrical graph has two halves that are mirror images of each other, meaning the data is evenly distributed around a central point.

Front

Can there be multiple peaks in a data distribution?

Back

Yes, a data distribution can have multiple peaks, which are points where the data is concentrated.

Front

What is a peak in a data distribution?

Back

A peak is a value in the data set where the frequency of data points is higher than in the surrounding values.

Front

What is a gap in a data distribution?

Back

A gap is a range of values in the data set where there are no data points, indicating a break in the distribution.

Front

How do you identify clusters in a dot plot?

Back

Clusters in a dot plot are identified by looking for groups of dots that are close together.

Front

What is the mode of a data set?

Back

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

Front

How can you display data visually?

Back

Data can be displayed visually using graphs such as dot plots, bar graphs, or histograms.

Front

What does it mean if there are gaps in a dot plot?

Back

Gaps in a dot plot indicate ranges of values where no data points are present.

Front

What is the significance of identifying peaks in data?

Back

Identifying peaks helps to understand where the most common values in the data set lie.
