Question

Which model is represented by the following graph? 

• A. Logistic regression model
• B. Simple Linear regression model
• C. Multiple linear regression model
• D. k nearest neighbor model

Hint:

Simple linear regression involves fitting a straight line to data to model the relationship between two variables.

Answer 1

The Correct Option is B

Step 1: Graph Interpretation.
The provided graph depicts a linear relationship between a dependent and an independent variable, indicating a simple linear regression model.

Step 2: Option Evaluation.
- (A) Logistic regression model: Rejected. This model is for binary outcomes and generates a sigmoid curve, not a straight line.
- (B) Simple Linear regression model: Accepted. This model accurately represents a straight-line relationship between variables.
- (C) Multiple linear regression model: Rejected. This model incorporates multiple independent variables, whereas the graph shows only one.
- (D) k nearest neighbor model: Rejected. This non-parametric model does not produce a straight line.

Step 3: Determination.
The appropriate model is (B) Simple Linear regression model.
