What is a mode in a data set?

Back

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

What is a cluster in data distribution?

Back

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

Front

What is the significance of the mean in a data distribution?

Back

The mean is the average of all data points and serves as a measure of central tendency.

Front

What does it mean if a distribution has a gap?

Back

A gap in a distribution indicates a range of values where no data points exist.

Front

What is the difference between a peak and a mode?

Back

A peak refers to the highest point in a graph, while the mode is the most frequently occurring value in a data set.
