A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation. Root Cause Analysis: In problem-solving efforts, scatter diagrams help identify potential root causes by examining their relationships with the observed issues.By analyzing the data points, practitioners can identify which variables are most influential in affecting product or process outcomes. In the above graph, you can see that the blue line shows an positive correlation, the orange line shows a negative corealtion and the green dots show no relation with the x values(it changes randomly independently). Quality Improvement: Scatter diagrams are frequently used in quality improvement projects, such as Six Sigma initiatives, to investigate the relationship between process variables and defects or variations. 1) If the value of y increases with the value of x.No Correlation: When data points appear randomly scattered with no clear trend, it implies no correlation or a weak relationship between the variables.This suggests that as one variable increases, the other tends to decrease. ![]() Negative Correlation: If data points predominantly trend downwards from left to right, it signifies a negative correlation. Scatterplots are really good for helping us see if two variables have positive or negative association (or no association at all).This means that as one variable increases, the other also tends to increase. ![]()
