How do you read Pearson’s r results?
High degree: If the coefficient value lies between ± 0.50 and ± 1, then it is said to be a strong correlation. Moderate degree: If the value lies between ± 0.30 and ± 0.49, then it is said to be a medium correlation. Low degree: When the value lies below + . 29, then it is said to be a small correlation.

How is Pearson r used in research?
Pearson’s correlation is utilized when you have two quantitative variables and you wish to see if there is a linear relationship between those variables. Your research hypothesis would represent that by stating that one score affects the other in a certain way. The correlation is affected by the size and sign of the r.
How does Pearson correlation work?
Pearson’s Correlation Coefficient is a linear correlation coefficient that returns a value of between -1 and +1. A -1 means there is a strong negative correlation and +1 means that there is a strong positive correlation. A 0 means that there is no correlation (this is also called zero correlation).
What are the assumptions of Pearson’s correlation coefficient?
The assumptions for Pearson correlation coefficient are as follows: level of measurement, related pairs, absence of outliers, normality of variables, linearity, and homoscedasticity. Level of measurement refers to each variable. For a Pearson correlation, each variable should be continuous.
What are Pearson’s r and scatterplots?
Scatterplots! Scatterplots! Pearson’s r is a numerical summary of the strength of the linear association between the variables. If the variables tend to go up and down together, the correlation coefficient will be positive. If the variables tend to go up and down in opposition with low values of one variable associated with high values of the
How do you calculate Pearson correlation coefficient?
The Pearson Correlation Coefficient (which used to be called the Pearson Product-Moment Correlation Coefficient) was established by Karl Pearson in the early 1900s. It tells us how strongly things are related to each other, and what direction the relationship is in! The formula is: r = Σ(X-Mx)(Y-My) / (N-1)SxSy.
