Cohen's benchmarks, the magnitude of this effect is:
a bar graph - Correct answer-which of the following graph formats is the best way
to examine an association claim between categorical variable and a quantitative
variable?
The presence of measured variables - Correct answer-which of the following
means a study used a bivariate correlational design?

following questions is NOT necessary to ask when interrogating statistical

, The way the sample was selected from the population - Correct answer-when
evaluating the external validity of an association claim, which of the following is
the most important issue to consider?
probability estimate - Correct answer-a study finds a correlation coefficient of

construct validity - Correct answer-If a person is asking whether the variables in an
association claim are measured appropriately, ________ is being interrogated.
casual inferences; made - Correct answer-Bivariate association claims' failure to
meet the criteria of temporal precedence and internal validity means that ______
