From the above matrix for
iriswe can deduce the following insights:
- Correlation between
Petal.Lengthis strong and dense.
Sepal.Widthseems to show very little correlation as datapoints are spreaded through out the plot area.
Petal.Widthalso shows strong correlation.
Note: The insights are made from the interpretation of scatterplots(with no absolute value of the coefficient of correlation calculated). Some more examination will be required to be done once significant variables are obtained for linear regression modeling. (with help of residual plots, the coefficient of determination i.e Multiplied R square we can reach closer to our results)
