What is the XY Scatter Plot | #Statistics #LeanSixSigma #OpEx #SixSigma #ASQGreenBelt #CSSGB

A Scatter diagram is a visual analysis tool that is meant to reflect the possible relationship between two variables.

The Scatter Plot visually plots pairs of data on an X-Y graph in order to reveal the relationship between the data sets.

The relationship between the two variables can be positive, negative or non-existent. The strength of the relationship can also be analyzed visually by how closely the points fall on the line of best fit.

The strength of that relationship can be expressed mathematically using the Pearson Correlation Coefficient, which is a number that ranges from a strong positive correlation (+1) to a strong negative correlation (-1).

The scatter plot is often used in the problem-solving process when we’re studying a process to understand which input variables (independent variables) are contributing to a negative outcome in a response variable (dependent variable).

Would have been better not drawing a line on the last plot (furthest down), since, like you say, there’s no correlation. I appreciate the content though! 🙏🏻
