Interval variables
Details
A simple data set is provided and you are asked to calculate three separate distance matrics. You should then use these to construct dendrograms using single linkage clustering. In order to simplify calculations there are only five cases and two variables (which share the same scale).
Case | x | y |
---|---|---|
1 | 1 | 2 |
2 | 3 | 2 |
3 | 6 | 6 |
4 | 10 | 7 |
5 | 8 | 8 |
Hint: Try plotting a simple sketch scatter graph first.
You should calculate distance matrices and dendrograms (single linkage) for the following distance measures:
Measure | Answers |
---|---|
Euclidean | |
Squared Eucliean | |
Manhattan (city block) |
