Thank you. Yes, I know it needs to use the "Replace Missing Values", but how can it replace them? Need to use min, max or average?
Hi @Noor_94_,
It depends of your dataset, and the analysis type. For example if you haven't outliers and high dispersed data a good selection may be replace the missing using the mean. if you have outliers a recomendation is to use the median.
another options could be use like replace with mode. In any case, one of the most powerful things about Rapidminer is that you can test the impact of multiple data preprocessing decisions in your models very quickly.
Test your decisions againts test dataset and meassure the results.

you need to use the "Replace Missing Values" for that.
