Which of the following is a common method for encoding categorical variables?
Step 1: Understand what categorical variables are. These are variables that represent categories or groups, like 'red', 'blue', or 'green'.
Step 2: Know that computers work better with numbers than with words. So, we need to convert these categories into numbers.
Step 3: Learn about Label Encoding. This is a method where each category is assigned a unique number. For example, 'red' could be 0, 'blue' could be 1, and 'green' could be 2.
Step 4: Realize that after encoding, you can use these numbers in mathematical models or algorithms.
