Why does a correlation table have a diagonal line of 1s? 1 Because the sum of all correlation coefficients must equal one. 2 Because it’s the result of a dummy variable. 3 Because p-values cannot be greater than one. 4 None of these 5 Because it acts as a benchmark for all other correlation coefficients.

Question

Why does a correlation table have a diagonal line of 1s?

1		Because the sum of all correlation coefficients must equal one.
2		Because it’s the result of a dummy variable.
3		Because p-values cannot be greater than one.
4		None of these
5		Because it acts as a benchmark for all other correlation coefficients.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
