SCENARIO Assume yоu аre using k-NN tо predict the оutcome for а new observаtion based on given data. The provided training dataset in the table below has credit scores for each of the 7 customers (A - G). You have a new customer (represented by X in the graph below) you need to predict the credit score for. The table below also shows the Euclidian distances between the new customer, X, and the 7 training customers. New - Existing Euclidian Credit Score X - A 1.19 684 X - B 0.65 727 X - C 0.96 817 X - D 1.17 604 X - E 1.74 730 X – F 1.82 781 X - G 1.57 618 The next two (2) questions are based on this scenario.
