# wcss calculation for multiple k-values

I cannot replicate the problem of calculating wcss for 6 different k-values for clustering.

The lecture produces the following results:

while lmy results show:

It is not clear what is being used as the input data - but assuming just the Longitude and Latitude vs country only there wcss values should be replicated.

Please help.

thanks,

Isaac

Hey Isaac,

Thank you for your question!

Given the information I have, what I can suggest is that you try to run the notebook from the resources called "6_4_how-to-choose-the-number-of-clusters-notebook". Simply open it and choose Cell -> Run All. See if you get the same values as those in the lesson. When I run it myself, the output is the same as the one presented.

Let me know how it went.

EDIT: Note that there is a `KMeans`

parameter called `random_state`

which, if set to `None`

(by default), initializes the centroids randomly. Set this parameter to an integer of your choice to get the same output every time you run the code.

Kind regards,
