A cluster is a group of data, or a bunch. A gap is a huge interval. An outlier is a piece of data that is really small or really big.
Gap: ina data display, a large space between data points.Ex. 3,4,5, Gap 20,22Cluster: in a data display, a cluster is several data points lie in a small interval. Ex. 7,8,9,0,2345678Outliers: A number ina set of data that is much larger or smaller than most of the other numbers in the set.Ex. 1, ( outlier ) 52, 55, 57,59, 129 (outlier)
The mean of the new data set is shifted from the mean of the original set, in the direction of the added cluster. We note that the same would be true if only a single new element were added.
