Image by the Author. The fact that the variables are non-correlated tells us just that there is no line that can describe the relationship between the variables: it doesn’t mean that the variables are not related at all! It just means that the relationship is not linear (and can be anything!) 2. Regression.
Statistics review 7: Correlation and regression - PMC
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC374386/#:~:text=The regression line is obtained using the method of least
The regression line is obtained using the method of least squares. Any line y = a + bx that we draw through the points gives a predicted or fitted value of y for each value of x in the data set. For a particular value of x the vertical difference between the observed and fitted value of y is known as the deviation, or residual (Fig. (Fig.8). 8 ...

Correlation. When a change in one variable is followed by a change in another variable, whether direct or indirect, this is known as correlation. If a change in one variable does not affect the other, the variables are said to be "uncorrelated." In a nutshell, it is a tool for determining the relationship between two variables.

Regression indicates the impact of a unit change in the known variable (x) on the estimated variable (y). Objective. To find a numerical value expressing the relationship between variables.
Correlation and Regression - Difference, Definition, Examples
https://www.cuemath.com/data/correlation-and-regression/#:~:text=The main difference between correlation and regression is that correlation
The main difference between correlation and regression is that correlation is used to find whether the given variables follow a linear relationship or not. Regression is used to find the effect of an independent variable on a dependent variable by determining the equation of the best-fitted line.

Below mentioned are a few key differences between these two aspects. ‘Correlation’, as the name says, it determines the interconnection or a co-relationship between the variables. ‘Regression’ explains how an independent variable is numerically associated with the dependent variable. In Correlation, both the independent and dependent ...

Regression is a type of statistical analysis that specifically estimates the relationship between a dependent variable and one or more independent variables. Difference between Correlation and Regression: Correlation vs. Regression. As mentioned above, “correlation” and “regression” can’t be used interchangeably.

https://byjus.com/maths/correlation-and-regression/#:~:text=Correlation and Regression Differences. There are some differences between Correlation
Correlation and Regression Differences. There are some differences between Correlation and regression. Correlation shows the quantity of the degree to which two variables are associated. It does not fix a line through the data points. You compute a correlation that shows how much one variable changes when the other remains constant.

Correlation does not capture causality, while regression is founded upon it. Correlation between x and y is the same as the one between y and x. Contrary, a regression of x and y, and y and x, yields completely different results. Lastly, the graphical representation of a correlation is a single point. Whereas, a linear regression is …

https://www.graphpad.com/guides/prism/latest/statistics/stat_the_difference_between_correla.htm#:~:text=Correlation computes the value of the Pearson correlation coefficient, r.
Correlation computes the value of the Pearson correlation coefficient, r. Its value ranges from -1 to +1. Linear regression quantifies goodness of fit with r2, sometimes shown in uppercase as R2. If you put the same data into correlation (which is rarely appropriate; see above), the square of r from correlation will equal r2 from regression.

While Correlation is typically used for bivariate analysis (involving two variables), Regression can be extended to multivariate analysis, involving more than two variables. Multiple Regression considers multiple independent variables, allowing for a more complex analysis of the relationships between variables.
