Linear regression analysis is used to determine how well one or more independent variables (predictors) explain or predict a dependent variable (outcome). It helps evaluate the strength and nature of relationships between variables.

===== - Identify Trends: It shows if there is a consistent relationship (positive or negative) between variables. =====
* Make Predictions: The regression line can be used to forecast values based on known data.
* Assess Suitability: By evaluating how closely data fits a linear model (e.g. using R²), we can judge whether the data supports a particular recommendation or conclusion.

===== 1. Plot the Data: Graph the independent vs. dependent variable to visually inspect the relationship. =====
# Fit a Line: Use statistical tools to calculate the best-fit line (regression line) through the data points.
# Analyze Metrics: - Slope: Indicates the direction and strength of the relationship. - R² (coefficient of determination): Shows how well the line fits the data (values closer to 1 indicate a strong fit).
# Draw Conclusions: If the data strongly follows the trend line and R² is high, the model supports using the data to justify a recommendation.

In summary, linear regression helps test if there's a meaningful, predictive relationship in the data that justifies a particular course of action.
