Question

shown below are the scatter plots for four data sets.
answer the questions that follow.
(a) choose the data set that has outliers.
data set in figure 1
data set in figure 2
data set in figure 3
data set in figure 4
(b) choose the two data sets that show clustering.
data set in figure 1
data set in figure 2
data set in figure 3
data set in figure 4

Explanation:

(a)

Step1: Analyze outliers

Outliers are data points that deviate significantly from the general pattern. In Figure 1, there is a point that is far away from the main cluster of points.

(b)

Step1: Analyze clustering

Clustering means data points group together. In Figure 2, there are two distinct groups of points. In Figure 3, there are also groups of points clustered together.

Answer:

(a) Data set in Figure 1.
(b) Data set in Figure 2, Data set in Figure 3.
