Question

In the context of Project based learning, the following question has to be solved-
What is the total population, total male population and total female population aged 10 to 24 in India?
Arrange the following solution steps to accomplish the same:
A. Read CSV file and check the shape of the DataFrame.
B. Identify the columns and the number of rows that you wants to use for plotting.
C. Create a new DataFrame containing the filtered data and Group data as per the requirement.
D. Plot data for the DataFrame.

• A. A, B, C, D
• B. D, B, C, A
• C. B, A, D, C
• D. C, B, D, A

Hint:

Visualization is always the final step of a data science task.
Thus, "Plot data" (D) must occur at the end of the pipeline, which makes option (A) the logical choice.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Data analysis workflows typically follow a structured pipeline: data ingestion, inspection, transformation, and visualization.

Step 2: Detailed Explanation:
1. A: Load data from the CSV into a pandas DataFrame and inspect its dimensions.
2. B: Identify relevant features (columns) needed for the specific analysis of age-groups.
3. C: Filter the data for age 10-24 and perform aggregation (grouping).
4. D: Visualize the results using a plotting library like Matplotlib or Seaborn.

Step 3: Final Answer:
The correct logical sequence is A, B, C, D.
