How to filter out examples with missing values!

Hello everyone! I am using the data set "Titanic" and am wondering how to filter out the examples with missing values. I see how to filter and see the ones with missing values, but not the other way around!

    Hi Court231,

    Or you could use the Replace Missing Values operator and the average (default) to fill missing numeric values. Or you could use the Impute Missing Values operator to estimate missing values. But you will be need to include the KNN operator in the subprocess for this to work. Look at the tutorial for Impute Missing values. I like this one because it doesn't apply one value to all missing. Works pretty good for the Titanic dataset.
