Practical Data Science using Python - EDA Project - 1

The video tutorial covers exploratory data analysis on Lending Club's dataset to identify factors leading to loan defaults. It begins with an introduction to the problem, followed by importing necessary libraries and the dataset. The tutorial then explores the dataset, emphasizing the need for manual feature selection to simplify analysis. A key transformation involves converting loan status into a binary format for easier analysis. The video also discusses statistical analysis using the describe function, handling missing values, and performing univariate analysis to understand loan amount distribution.

What is the primary goal of the exploratory data analysis task assigned by Lending Club?

• To reduce the interest rates on loans

• To identify features responsible for higher default rates

• To expand the customer base

• To increase the number of loans disbursed

Which library is used for numeric array management in the analysis?

• Pandas

• Matplotlib

• Numpy

• Seaborn

Why is it necessary to drop certain columns from the dataset?

• To simplify the analysis by focusing on relevant features

• To improve the speed of data loading

• To enhance the visualization quality

• To reduce the file size

What does the 'loan status' column indicate?

• Whether the borrower has defaulted or not

• The type of loan

• The duration of the loan

• The interest rate of the loan

How is the 'charged off' status represented in the new 'defaulted' column?

• As a 0

• As a 3

• As a 1

• As a 2

What is the purpose of using a Lambda function in this analysis?

• To visualize data

• To transform loan status values

• To perform statistical analysis

• To import data

What statistical information does the describe function provide?

• Visualizations of data

• Missing values count

• Data types of columns

• Statistical values like mean and quartiles

Why is it important to identify outliers in the dataset?

• To increase the dataset size

• To ensure data is normally distributed

• To improve data visualization

• To enhance data security

Which function is used to identify missing values in the dataset?

• describe

• info

• drop

• apply

What does the histogram of loan amounts help us understand?

• The average loan amount

• The total number of loans

• The interest rates of loans

• The distribution and concentration of loan amounts
