Question

Can I choose 5 for number of clusters after WCSS has run? Because your solution suggest 2 instead, but I think 5 is more optimal in this case...it does not include language with it...why would you suggest 2 cluster instead of 5?

Answer 1

Hey Sherine,

Thanks for reaching out!

The instructor recommends choosing 2 or 3 clusters as the optimal solution based on the WCSS plot accessible from the provided code.

This plot reveals a sharp decline in WCSS values from 1 to approximately 3 clusters. Although increasing the cluster count to 4, 5, and beyond continues to lower the WCSS, this occurs at a slower rate. Ultimately, the choice of the number of clusters to use depends on the developer's judgment and the specific requirements of the task at hand.

Hope this helps!

Kind regards,
