KNN questions a. Make up a set of three records, each with two numeric predictor variables and one categorical target variable, so that the classification would not change regardless of the value of k. b. Refer to Exercise a. Alter your data set so that the classification changes for different values of k. c. Refer to Exercise b. Find the Euclidean distance between each pair of points. Using these points, verify that Euclidean distance is a true distance metric.
