Answer the following questions.
distributions have two scores for each individual. a is a picture of the relationship between two variables.
analysis is designed to examine linear relationships between variables.a is an index that describes the direction and of a relationship. a correlation means that higher scores on y are associated with higher scores on x, and low scores on y correspond to low scores on x.
when we want to find the correlation between two continuous variables, the correlation is used. 's rho is a method of correlation for finding the association between two sets of ranks. correlation expresses the relationship between a continuous variable and an artificial dichotomous variable.
the statistical significance of a correlation coefficient is tested by using the . the significance level is symbolized as a .
.
analysis is used to make predictions about scores on one variable from knowledge of scores on another variable. predictions are obtained from the line, which is defined as the line through a set of points in a scatter diagram.
the slope of the regression equation is the and the value of y when x is 0 is the . the difference between the observed score and predicted score is called the .
the standard deviation of the residuals is known as the .
the correlation coefficient squared is known as the , which tells us the proportion of the variance in one variable explained by the other variable.
the is a measure of non-association between two variables.
