How exactly do I plot (1.4-practical) in Excel

This is a far as I get in Excel — k-means practical Excel.

So, how did you plot the one in Silhouette plot VDO?

I thought we plotted the data in 2D graph as you’ve done. No need for Silhouette plot. I may be wrong?

I think the plot in 2d was what was asked for and should be good. I was searching online as to how to plot the Silhouette plot in R. The reason being that when I did my 2d plot prior to the K-means clustering, I assumed the k value to be 3, based on the plot generated before applying K-means ( just visual check). I think the Silhouette plot can help confirm if our cluster number is good.

The better the Silhouette coefficient, the better the clustering that we got. Still learning through 🙂

This graph, actually.

Would be nice if I can add hovering dialog box (to tell which point) as well.
