Data Science Interview Question 12

Which Strategy you should choose to deal with missing values and why?

  • The first strategy is to remove the entire row containing a missing value.

  • This is not a bad idea, but it can only be considered when the data is very large.

  • If removing missing values results in a data shortage, then this will not be an ideal dataset for any data science task.

  • This is where the second strategy comes in, which is to the mean, median, or mode of the other known values.

  • This strategy can be considered in any type of dataset.
