Overview of Important Statistical Tests
• Multiple regression is the method of analysis that
A) Uses several independent variables to predict the category to which a participant belongs
B) Describes the relationship between a predictor and an outcome variable
C) Describes the effect of an independent variable on two or more dependent variables
D) Uses several independent variables to predict the score of a participant
• The variable that is predicted is called the
A) criterion variable.
B) predictor variable.
C) effect variable.
D) regression variable.
• MANOVA is the method of analysis that
A) Uses several independent variables to predict the category to which a participant belongs
B) Describes the relationship between a predictor and an outcome variable
C) Describes the effect of an independent variable on two or more dependent variables
D) Uses several independent variables to predict the score of a participant
• When would it be appropriate to use a MANOVA?
A) To examine the effects of noise and room temperature on reading comprehension
B) To predict performance on a reading comprehension test from participant educational level
C) To examine the effect of practice or no practice on reading comprehension and reading speed
D) Both A and C
• The "C" in MANCOVA refers to:
A) Covariates of the independent and dependent variables
B) Covariates of the independent variables
C) Covariates of the dependent variable(s)
D) Covariates of the criterion
• When would it be appropriate to use a MANCOVA?
A) To examine the effects of practice, noise, and room temperature on reading comprehension and reading speed
B) To predict performance on a reading comprehension test from participant educational level
C) To examine the effect of practice or no practice on reading comprehension and reading speed
D) Both A and C
• For which of the following studies would Factor Analysis be the correct statistical test?
A) To examine the effects of practice, noise, and room temperature on reading comprehension and reading speed
B) To predict performance on a reading comprehension test from participant educational level
C) To identify items on a reading test, that are interrelated and that together identify underlying constructs, such as comprehension or reading speed
D) To examine the effect of practice or no practice on reading comprehension and reading speed
Both A and C
• Use Factor Analysis when
A) the goal is to use the values of more than one variable to predict the value of another variable
B) the goal is to represent variables as a smaller number of more general constructs
C) the goal is to make sure that that test items actually measure the hypothesized construct
D) both B and C
