A Pearson product-moment correlation was run to determine the relationship between an individual's height and their performance in a long jump (distance jumped). The data showed no violation of normality, linearity or homoscedasticity. There was a strong, positive correlation between height and distance jumped, which was statistically significant

Pearson Correlation Formula- Pearson correlation ...
The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales). The significance test for r evaluates whether there is a linear ...

There are two correlation tests that are commonly used – Pearson’s product moment correlation and Spearman’s rank correlation. If each of the measures being tested are continuous and normally distributed without outliers the Pearson’s product moment correlation is the most appropriate test to use and if not, the Spearman’s rank ...

Correlation can be used in a causal research hypothesis if the study is a true experiment. Correlation can also be used in an associative hypothesis becuase Pearsons r is bivariate. Correlation cannot be used in an attributive hypothesis. Pearson's correlation is used when you are working with two quantitative variables in a population.

That is where Pearson’s product-moment correlation coefficient comes in handy: where sx and sY refer to the standard deviations of X and Y, and zX and zY refer to standardized values of X and Y. A couple of relationships between the correlation coefficient and regression are worth noticing. First, we defined the slope of the line, b, as , and ...

Both lambda and Pearson's product moment correlation are based on guessing the mean. ANS: F. 11. Pearson's product moment correlation indicates how much of the variance in the dependent variable has been explained. ANS: T. 12. The general format for the regression line is y = a + b (X). The only observed quantity in this expression is X.
