Question: In which scenario would you prefer using a linear regression model?

Options:

When the outcome variable is categorical
When the relationship between variables is non-linear
When you need to predict a continuous variable based on other continuous variables
When you have a small dataset

Correct Answer: When you need to predict a continuous variable based on other continuous variables

Solution:

Linear regression is preferred when predicting a continuous outcome variable based on one or more continuous predictor variables.

When the outcome variable is categorical
When the relationship between variables is non-linear
When you need to predict a continuous variable based on other continuous variables
When you have a small dataset

In which scenario would you prefer using a linear regression model?

Step 1: Identify the type of outcome you want to predict. Is it a continuous number, like height, weight, or temperature?
Step 2: Check if you have one or more predictor variables that are also continuous. For example, age, income, or hours studied.
Step 3: If both the outcome and predictor variables are continuous, then a linear regression model is a good choice.
Step 4: Consider if the relationship between the predictor variables and the outcome is linear, meaning it can be represented by a straight line.

Linear Regression – A statistical method used to model the relationship between a dependent variable and one or more independent variables, particularly when the dependent variable is continuous.
Continuous Outcome Variable – A variable that can take on an infinite number of values within a given range, such as height, weight, or temperature.
Predictor Variables – Variables that are used to predict the value of the outcome variable in a regression model.
