Question

When is Pearson correlation coefficient positive? What occurs for the coefficient to be rejected?

Answer 1

When the relationship between the variables is positive that means when the independent variables increases the dependent variable also increases hence forth leads to positive correlation.

The correlation coefficient can only be rejected if the correlation coefficient is either less than the critical correlation or greater than the critical correlation coefficient at the given confidence level that is computed using the critical value table of correlation coefficient and the degree of freedom which is n-2.
