It is r.
The answer is r.Actually 'r' is the usual symbol for the correlation coefficient statistic calculated for a sampleof paired values. The correlation coefficient for a population of pairs of random variables distributed according to a binomial normal distribution is usually denoted by the Greek letter 'rho'.

μ is the symbol for the population mean in statistics. fyi and related but not necessary for the above answer: the sample mean is , enunciated by saying "x" bar. hope this helped. Citation : http://en.wikipedia.org/wiki/Arithmetic_mean
In statistics, this is the symbol for the "Variance"
The mean is typically represented by the symbol ( \mu ) (mu) when referring to the population mean, and by ( \bar{x} ) (x-bar) when referring to the sample mean. These symbols are widely used in statistics to denote the average value of a set of data points.
The Correlation Coefficient computed from the sample data measures the strength and direction of a linear relationship between two variables. The symbol for the sample correlation coefficient is r. The symbol for the population correlation is p (Greek letter rho).
The symbol for the correlation coefficient is typically denoted as "r" when referring to Pearson's correlation coefficient. This statistic measures the strength and direction of the linear relationship between two variables. In the context of other correlation methods, such as Spearman's rank correlation, the symbol "ρ" (rho) is often used.
The answer is r.Actually 'r' is the usual symbol for the correlation coefficient statistic calculated for a sampleof paired values. The correlation coefficient for a population of pairs of random variables distributed according to a binomial normal distribution is usually denoted by the Greek letter 'rho'.
lower case "r"
n
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.
The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.
In statistics, the symbol ( S ) typically represents the sample standard deviation, which measures the amount of variation or dispersion in a set of sample data. It quantifies how much individual data points deviate from the sample mean. The formula for calculating ( S ) involves taking the square root of the variance, which itself is the average of the squared differences between each data point and the sample mean. This metric is crucial for understanding the spread of data in inferential statistics.
3M uses RA as the symbol for the coefficient of retroreflection.
μ is the symbol for the population mean in statistics. fyi and related but not necessary for the above answer: the sample mean is , enunciated by saying "x" bar. hope this helped. Citation : http://en.wikipedia.org/wiki/Arithmetic_mean
s is the sample standard deviation. it is computed by taking the square root of: sum(x-mean)2/n-1
In statistics, this is the symbol for the "Variance"
