What is the term for data that our group closely together outlier linear positive clustering

The term for data that are grouped closely together, excluding outliers, and exhibit a positive linear relationship is Positive Linear Clustering.

This implies that as one variable increases, the other one also tends to increase and they tend to cluster around some sort of line (hence, linear), excluding outliers. This is often measured using the correlation coefficient in statistical analyses.

The term that describes data points that are closely grouped together and exhibit a linear positive clustering pattern, with a few outliers, is called "clustered data with outliers."
