This is called a scatter diagram, which represents a visual way to check for a positive or negative correlation. The formula for the Pearsons r is complicated, but most computer programs can quickly churn out the correlation coefficient from your data. In other words, it reflects how similar the measurements of two or more variables are across a dataset. But if your data do not meet all assumptions for this test, youll need to use a non-parametric test instead. Tags: Question 15 . .68. r = -0.95. r = 0. r = 0.85 Strong Negative. Making option A the right answer to the question. answer choices. One of the most common ways to quantify a relationship between two variables is to use the Pearson correlation coefficient, which is a measure of the linear association between two variables. The correlation coefficient tells you how closely your data fit on a line. If the trendline of a scatterplot slopes downwards from the left to your right, it shows that as one variable increases, the other one is decreasing, thus, depicting a negative correlation between the two Weak Negative.
