shown below are the scatter plots for four data sets. answer the questions that follow. (a) choose the two data sets that have outliers. (b) choose the data set that shows clustering.
Answer
Explanation:
Step1: Identify outliers
Outliers are data - points that are far from the other data - points. In Figure 2, there are points that are separated from the main group of points. In Figure 4, the single point at the top is far from the other points.
Step2: Identify clustering
Clustering is when data - points group together. In Figure 2, we can see three distinct groups of points.
Answer:
(a) Data set in Figure 2, Data set in Figure 4 (b) Data set in Figure 2
