0. Suppose there are five instances, i1, i2, i3, i4, i5 in a dataset having three features, X,Y and Z as shown in the table below:
Instances X Y Z
i1 1.6 2.3 5.1
i2 2.4 2.5 4.6
i3 3.9 3.6 3.7
i4 4.1 3.7 2.5
i5 5.6 8.3 1.8
In order to find the dependence between two variables we use the Pearson's Correlation Coefficient. Based on your understanding of Correlation Coefficient, choose the correct option/s:
1. A strong positive correlation between X and Y
2. A strong negative correlation between X and Y
3. A weak positive correlation between X and Z
4. A weak negative correlation between X and Z
