Assertion and Reasoning Questions:
Direction: Questions 2-3, consist of two statements – Assertion (A) and Reasoning (R). Answer these questions
by selecting the appropriate option given below:
a. Both A and R are true and R is the correct explanation of A.
b. Both A and R are true but R is not the correct explanation of A.
c. A is true but R is false.
d. A is false but R is true.
2. Assertion: Data preprocessing is essential in machine learning to optimise datasets for effective model training.
Reasoning: This phase involves cleaning, transforming, and normalizing data, ensuring that machine learning
algorithms can interpret and learn from the data effectively.
3. Assertion: Data visualisation using Python’s Matplotlib library simplifies the process through its ‘pyplot’ submodule,
offering a user-friendly interface akin to MATLAB.
Reasoning: Matplotlib’s pyplot submodule includes convenient functions that streamline the creation of basic
plots, enhancing the visual representation and interpretation of data.
