A probabilistic relationship is one for which
A)the value of the dependent variable is perfectly determined by the value of the independent variable.
B)all data points fall on the same line.
C)there is no random error component.
D)the value of the dependent variable is related to the value of the independent variable but the data points do not fall on the same line.

Question

Quizplus · Accepted Answer

A probabilistic relationship means that there is a relationship between the independent and dependent variable, but there is some random error or variability in the data. This means that the data points do not fall on the same line, but rather a line of best fit can be used to estimate the relationship between the variables. Choice A is incorrect because a perfect relationship would not have any random error component. Choice B is incorrect because it implies that all the data points fall on a straight line, which may not be the case in a probabilistic relationship. Choice C is incorrect because it contradicts the definition of a probabilistic relationship which has a random error component.
