Linear Regression and Data Prediction

This tutorial covers predicting home prices using simple linear regression in Python. It explains the linear equation, its components, and how to implement it using sklearn. The video demonstrates predicting home prices based on area and exporting results to a CSV file. It also includes a visualization of the linear equation and an exercise for further practice.

What is the primary goal of using simple linear regression in this tutorial?

• To predict weather patterns

• To predict car prices

• To predict stock prices

• To predict home prices

What is the basis for predicting home prices in the dataset?

• Number of bedrooms

• Age of the home

• Location of the home

• Area of the home

What type of plot is used to visualize the relationship between home prices and area?

• Bar plot

• Line plot

• Scatter plot

• Pie chart

Why is the blue line chosen as the best fit line in linear regression?

• It passes through all data points

• It is the shortest line

• It minimizes the error between predicted and actual values

• It is the longest line

In the linear equation y = mx + b, what does 'm' represent?

• Independent variable

• Dependent variable

• Slope

• Intercept

Which library is primarily used for linear regression in this tutorial?

• Matplotlib

• Pandas

• Scikit-learn

• NumPy

What is the first step in loading data for analysis in Python?

• Creating a scatter plot

• Exporting the data to CSV

• Training the model

• Importing the data into a pandas DataFrame

What does fitting the data to a model mean?

• Visualizing the data

• Training the model with the data

• Exporting the data

• Ignoring the data

How is the price of a home predicted using the trained model?

• By using a decision tree

• By using a random number generator

• By using the linear equation derived from the model

• By guessing

What is the purpose of generating a new CSV file with predictions?

• To delete the original data

• To create a backup of the model

• To store the predicted prices for multiple areas

• To visualize the data
