Types of research questions a Pearson correlation can examine: Is there a statistically significant relationship between age, as measured in years, and height, measured in inches? Genotype-environment correlations refer to genetic differences in exposure to particular environments. Psychologists use a statistic called a correlation coefficient to measure the strength of a correlation (the relationship between two or more variables). when one variable increases the other on an average also increases and if one variable decreases the other also decreases.The correlation is said to . Linearity assumes a straight line relationship between each of the two variables and homoscedasticity assumes that data is equally distributed about the regression line.
