A correlation coefficient is a statistical measure that indicates the degree of association between two variables. It measures the strength and direction of the linear relationship between two sets of data.
The formula for calculating the correlation coefficient is: r = (nΣxy - ΣxΣy) / sqrt[(nΣx^2 - (Σx)^2)(nΣy^2 - (Σy)^2)].
The correlation coefficient value ranges from -1 to +1, where -1 represents a perfect negative correlation, 0 represents no correlation, and +1 represents a perfect positive correlation. The closer the value is to -1 or +1, the stronger the correlation is between the two variables.
You can use the correlation coefficient to analyze the relationship between two variables and make predictions based on the data. For example, if you find a strong positive correlation between the amount of exercise someone does and their weight loss, you could predict that someone who exercises more will lose more weight.
Simply input your data points into the calculator, and it will automatically calculate the correlation coefficient for you. You can also choose to display a scatter plot of the data to visualize the relationship between the variables.
