300
The relationship between two variables that resembles a straight line.
What is linearity?
300
The hypothesis to be; usually states that there is no relationship between two or more variables.

What is expected frequency?
500
A visual display of the correlation between two variables that looks like a cloud of scattered dots.
What is a scatter plot?
500
The p value associated with a result supporting a prediction of a nonspecific direction of a research result; e.g., either MA MB or MB MA or the sign of r is either positive or negative.
What is a two-tailed p value?
500
A test of significance used to judge the tenability of the null hypothesis of no relationship between two variables.
