shown below are the scatter plots for four data sets. answer the questions that follow. (a) choose the data set that has outliers. (b) choose the two data sets that show clustering.
Answer
Explanation:
Step1: Identify outliers
Outliers are data - points that are far from the other data - points. In Figure 4, there is a data - point that is separated from the main group of data - points. So, the data set with outliers is Figure 4.
Step2: Identify clustering
Clustering occurs when data - points group together in subsets. In Figure 2 and Figure 4, we can see distinct groups or clusters of data - points.
Answer:
(a) Data set in Figure 4 (b) Data set in Figure 2, Data set in Figure 4
