Question 2

+2 marksOne correct option

You are working on a machine learning project and have received a dataset containing numeric and categorical features. The dataset has some missing values and potential outliers. Given the following data cleaning steps:

  1. Use One-Hot Encoding for categorical variables.
  2. Impute missing values with feature’s mean for numeric features.
  3. Remove duplicates.
  4. Standardize numeric features using Z-score normalization.
  5. Identify and handle outliers using the IQR method.
