In statistical analysis, Correlation is measured by a coefficient denoted by “r”. Let’s assume a set of data labeled by two variables, X and Y. Thus, the Correlation Coefficient can be formulated as: Where, x̄ and ȳ are the sample means AVERAGE of X variable and AVERAGE of Y ...

The next step is to convert the Pearson correlation coefficient value to a t-statistic. To do this, two components are required: r and the number of pairs in the test (n). In order to determine the number of pairs, simply count them manually or use the count function (=COUNT). Each...
You can calculate R-squared in Excel using several methods. The simplest way is to get two data sets and use the built-in R-squared formula. Another alternative is to find a correlation and then square it. Both are shown here: How Do I Find R-Squared in Excel?
population, particularly of cells of a plant, the rate of gain of a new mass per unit of time at all times t can be a function of important internal or environmental parameters, also of the same accumulated mass as a limiting element to growth (dense dependence with negative correlation)....
