Question

Identify two situations in which criminologists or criminal justice policy analysts might use linear regression to describe and/or test a relationship. One of these must involve a positive hypothesized relationship; one a negative hypothesized relationship. Do not use examples from the text, lecture or live classroom. Does the absence of a straight line relationship (r between -.05 and +.05, for instance) mean that there is no relationship between the variables? Support your conclusion with examples.

Answer 1

If two situations in which criminologists or criminal justice policy analysts might use linear regression to describe and/or test a relationship.

If their is no straight line linear relationship then it will be non linear relationships in variables.

such that quadratic realationship or other relationship.

Or may be weak linear relationship also present in the data.so u have to add other independent variables in the data.
