- Pearson correlation coefficient - Wikipedia
In statistics, the Pearson correlation coefficient (PCC) [a] is a correlation coefficient that measures linear correlation between two sets of data It is the ratio between the covariance of two variables and the product of their standard deviations; thus, it is essentially a normalized measurement of the covariance, such that the result always

As part of the ongoing series in Anesthesia Analgesia, this basic statistical tutorial discusses the 2 most com-monly used correlation coeficients in medical research, the Pearson coeficient and the Spearman coeficient 3 It is important to note that these correlation coeficients are frequently misunderstood and misused 4,5 We thus focus on
- Pearson Correlation Coefficient (r) | Guide Examples - Scribbr
The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables

In the present paper, we discuss the Pearson, Spearman, Kendall correlation coefficients and their statistical analogues We propose a new correlation coefficient r and its statistical analogue
- Pearson Correlation Coefficient - GeeksforGeeks
Pearson Correlation Coefficient (PCC) is used for measuring the strength and direction of a linear relationship between two variables It is important in the fields like data science, finance, healthcare and social sciences where understanding relationships between different factors is important
- Correlation coefficients: Appropriate use and interpretation
The Pearson correlation coefficient is typically used for jointly normally distributed data (data that follow a bivariate normal distribution) For nonnormally distributed continuous data, for ordinal data, or for data with relevant outliers, a Spearman rank correlation can be used as a measure of a monotonic association
- Pearson Correlation - Technology Networks
In this article, we will explore the theory, assumptions and interpretation of Pearson’s correlation, including a worked example of how to calculate Pearson’s correlation coefficient, often referred to as Pearson’s r What is Pearson correlation test, Pearson product moment correlation or Pearson r?
- 18. 1 - Pearson Correlation Coefficient | STAT 509
The Pearson correlation coefficient measures the degree of linear relationship between X and Y and \ (-1 ≤ r_ {p} ≤ +1\), so that \ (r_ {p}\) is a "unitless" quantity, i e , when you construct the correlation coefficient the units of measurement that are used cancel out
