• Shape.
• Unusual features.

What are the examples of set of data?

A data set is a collection of numbers or values that relate to a particular subject. For example, the test scores of each student in a particular class is a data set. The number of fish eaten by each dolphin at an aquarium is a data set.

How do you characterize a data set?

1 Methods for Describing a Set of Data

1. The central tendency of the set of measurements: the tendency of the data to cluster, or center, about certain numerical values.
2. The variability of the set of measurements: the spread of the data.

What is the set of data all about?
