Least Squares Regression

A statistical method used to determine the line of best fit by minimizing the sum of squares of the differences between observed values and those predicted by a linear model.

P-value

The probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct.

Significant

Indicating a statistically meaningful relationship or difference in data, often determined by achieving a p-value below a predefined threshold.

Least Squares Regression

A statistical method used to determine the line of best fit by minimizing the sum of squares of the residuals.
