shown below are the scatter plots for four data sets. answer the questions that follow. (a) choose the data set that shows clustering. (b) choose the two data sets that have outliers.
Answer
Explanation:
Step1: Identify clustering
Clustering is when data - points group together. In Figure 2, the data - points form two distinct clusters.
Step2: Identify outliers
Outliers are data - points that are far from the rest of the data. In Figure 1, there are points that are far from the general pattern of the other points. In Figure 3, there is a point that is away from the linear - like pattern of the other points.
Answer:
(a) Data set in Figure 2 (b) Data set in Figure 1, Data set in Figure 3
