Ann Marie would like to test her hypothesis. To do that, she needs to show groups of data that are similar in some way. Which data-mining techniques should she use?

Clustering Analysis

Explanation:

Clustering analysis or otherwise called cluster analysis is a task composed of grouping sets of objects in a way that objects in the same group tend to be more similar to each other than to objects in some other groups. Like the question said, Ann would love to show groups of data that are similar in some way. This makes Clustering analysis the perfect choice of pick, because of the similarity that's needed. A result of cluster analysis is capable of being used in the creation of something like customer profiling.

he could use bold or bigger text just a suggestion.
