D- 1,2 = (4-1) + (3-5) Chebyshev Method [(3) + (-2)]
D- 1,2 = [Absolute value of (4-1) + (3-5)] Minkowski Method [(3) + (2)]
D- 1,2 = Square root of {[4-1]2 + [3-5]2 } Euclidian Distance [(3) + (-2)]
D- 1,2 = {[4-1]2 + [3-5]2} Squared Euclidian Distance – Most utilised method used to calculate the distance between people. [(9) + (4)]
59.222-40.667 = 18.555
40.667-11.80 = 28.867
The difference suddenly increased from 18.555 to 28.867. So we have to stop the calculations & the no of clusters for the data is 2 (Bottom up approach).
Hence a 2 cluster table. Hierarchical Cluster – To find no of segments.

K Means Cluster analysis
Cluster no 1 becomes a very important cluster (16 out of 25 people) in which they give least
importance to Try new things & being part of a changing world (Rating being 1) & give most importance to Indian technology & buy made in India (rating being 4).
Also we can see that the cluster contains people in the age category of 41 – 50 (from cluster membership table)
Mention for each statement which cluster is giving more importance. (Observe the rating & decide accordingly).
1. Create a new product (PEN). 3 Main features of a Pen. (Conjoint Analysis)
Ink – Blue, Black, Red
Grip – Rubber, Plastic
Price – 2, 5, 10
Make the 18 combinations using the data above & get ranking of the combinations (best being 1 & the least being 18) from atleast 5 respondents (write the combinations & the average rank).
2. A new product (Soap) Lux, Liril, Lifebuoy, Hamam, Pears, Dove, Medimix (Multi-dimensional scaling)Make 21 combinations (7*6/2) & rank each of the combinations by the following method: (1= highly similar, 2 = similar, 3=neutral, 4= dissimilar, 5= highly dissimilar)Get the ranking of each combination from atleast 5 respondents & get the combination along with the average rank.
