shown below are the scatter plots for four data sets. answer the questions that follow. (a) choose the data set that has an outlier. (b) choose the two data sets that show clustering.
Answer
Explanation:
Step1: Identify outlier
An outlier is a data - point that is far from other data - points. In Figure 1, there is a point that is separated from the general linear pattern of the other points.
Step2: Identify clustering
Clustering means data - points group together. In Figure 2, there are two distinct groups of points, and in Figure 4, there are also two groups of points.
Answer:
(a) Data set in Figure 1 (b) Data set in Figure 2, Data set in Figure 4
