What Is A Weak Positive Correlation A positive correlation means that both variables change in the same direction A negative correlation means that the variables change in opposite directions A zero correlation means there s no relationship between the variables
A weak positive correlation indicates that although both variables tend to go up in response to one another the relationship is not very strong A strong negative correlation on the other hand indicates a strong connection between the two variables but that one goes up whenever the other one goes down A correlation of 1 indicates a perfect positive correlation meaning that as one variable goes up the other goes up There is no rule for determining what correlation size is considered strong moderate or weak

It means that separately each independent variable IV has a positive correlation with the dependent variable DV As each IV increases the DV tends to increase However it is a fairly weak correlation Additionally these correlations don t control for confounding variables A correlation coefficient greater than zero indicates a positive relationship while a value less than zero signifies a negative relationship A value close to zero indicates a weak
6 Examples of Correlation in Real Life In statistics correlation is a measure of the linear relationship between two variables The value for a correlation coefficient is always between 1 and 1 where The following examples illustrate real life scenarios of negative positive and no correlation between variables Weak positive correlation When one variable increases the other variable tends to increase as well but in a weak or unreliable manner Weak negative correlation When one variable increases the other variable tends to decrease but in a weak or unreliable manner

The main takeaway here is that even when there is a positive correlation between two things you might not be able to see it if your sample size is small For example you might get unlucky with the one sample that you measured Your sample could show a negative correlation even when the actual correlation is positive The Pearson correlation coefficient r is the most common way of measuring a linear correlation It is a number between 1 and 1 that measures the strength and direction of the relationship between two variables
The low level of the p value reassures us that 99 99 of the time the correlation is weak at an r of 0 31 In this context the utmost importance should be given to avoid misunderstandings when reporting correlation coefficients and naming their strength The sign of the correlation coefficient reflects the direction of the linear association between the two variables the correlation coefficient is positive whenever the line of best fit has a positive slope and negative whenever the line of best fit has a negative slope
