how can I change K values?
for my data science class we need to do different assignments wirth RapidMiner. I don't get a thing tbh! 
We have to cluster the data set using K-means. I did that and now we should experiment with K-values und tell what values make sense. But how can I change them and what does a K-value tell me?
