scatterplot
a figure that graphically represents the relationship between two variables.

type of relationships
 positive: variabe increase and decrease together.
 negative: as one variable increases, the other decreasesan inverse relationship.
 none: variables are unrelated and do not move together in any way.
 curvilinear: vvariabes increase together up to a point and then, as one continues to increase, the other decreases.

causality
the assumption that correlation indicates a causal relationship between the two variables.

directionality
the inference made with respect to the direction of a causal relationship between two variables.

thirdvariable problem
the problem of a correlation between two variables being dependent on another (third) variable.

restrictive range
a variable that is truncated and has limited variability

partial correlation
a correlational technique that involves measuring three variables and then statistically removing the effect of the third variable fro the correlation of the remaining two variables.

personwho argument
arguing that a wellestablished statistical trend is invalid because we know a "person who" went agaist the trend.

Pearson productmoment correlation coefficient (Pearson's r)
the most commonly used correlation coefficient when both variables are measured on an interval or ration scale.

coefficient of determination (r^{2})
a measure of the proportion of the variance in one variable that is accounted for by another variable; calculated by squaring the correlation coefficient.

Spearman's rankorder correlation coefficient
the correlation coefficient used when one (or more) of the variables is measured on an ordinal (ranking) scale.

pointbiserial correlation coefficient
the correlation coefficient used when one of the variables is measured on a dichotomous nominal scale and the other is measured on an interval or ratio scale.

phi coefficient
the correlation coefficient used when both measured variables are dichotomous an nominal.

regression analysis
a procedure that allows us to predict an individual's score on one variable based on knowing one or more other variables.
