In correlation, "r" represents the correlation coefficient, a statistical measure that quantifies the strength and direction of the linear relationship between two variables. It ranges from -1 to +1, where +1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 signifies no correlation at all. The value of "r" helps to understand how closely the two variables move together.
What else can I help you with?
What does the r stand?
The "r" typically stands for the correlation coefficient in statistics, which measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation. In other contexts, "r" can also represent other concepts, such as the radius in geometry or the resistance in electrical engineering, depending on the subject matter.
If the coefficient of determination is .767 what is correlation between the two variables?
The coefficient of determination, denoted as ( R^2 ), indicates the proportion of variance in one variable that can be explained by another variable. To find the correlation coefficient ( R ), you take the square root of ( R^2 ). In this case, if ( R^2 = 0.767 ), then the correlation ( R = \sqrt{0.767} \approx 0.875 ). This indicates a strong positive correlation between the two variables.
If there is no correlation r is equal to?
0, within statistical error.
What does r value represent?
The r value, or correlation coefficient, quantifies the strength and direction of a linear relationship between two variables. Its value ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 signifies no correlation. A higher absolute value of r indicates a stronger relationship, while the sign indicates the nature of the relationship.
What is the r value in math?
In mathematics, the "r value" typically refers to the correlation coefficient, denoted as "r," which measures the strength and direction of a linear relationship between two variables. Its value ranges from -1 to +1, where +1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 implies no correlation at all. The r value is commonly used in statistics to assess how closely data points cluster around a line of best fit.

What is the value of correlation coefficient r for perfect positive correlation?
1.
What type of correlation do you have when are is equal to one?
A correlation coefficient of 1 (r=1) is a perfect positive correlation.
Does statistical correlation r have units?
No, r is a coefficient.
What is the feasible range for r the correlation coefficient?
the correlation coefficient range is -1 to +1
What does COSPEC stand for?
COSPEC stands for Correlation Spectrometer.
Interpret an r value of 0.11?
a strong negative correlation* * * * *No it is not. It is a very weak positive correlation.
Which is the stronger correlation?
The stronger correlation will be the one whose absolute value is closest to one. For example, r = -.78 is stronger than r=.65, because: |r| = |-.78| = .78 > |r| = |.65| = .65

What does the science symbol r mean?
In science, the symbol "r" typically refers to the correlation coefficient, which measures the strength and direction of a relationship between two variables. It ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.
What is weak correlation?
R less than 0.3
Is the correlation coefficient r a resistant measure of association?
no
