EDUC 815 Quiz: Correlational Designs
- If a researcher wishes to determine how well a combination of predictor variables correlates with a composite of several criterion variables, the appropriate statistical technique to use is
- The multiple correlation coefficient between predictor variables and grades is .50. This finding means that
- An important factor in deciding which correlational technique to use is
- If every point in a scattergram plotting variable X and variable Y falls on the line of best t, we can conclude that
- A correlation matrix is used to
- Path analysis is an appropriate statistical technique when
- Prediction research can be done for the purpose of
- A correlation coefficient of .20 between two variables
- If every increase in score on a test of literary knowledge is accompanied by an increase in score on an intelligence test, one can conclude that
- If the relationship between two variables is markedly nonlinear, the researcher should determine the degree of relationship by computing a
- Multiple regression involves
- Hierarchical linear modeling is a statistical technique that can be used for understanding
- A scattergram can detect
- “To provide the most powerful test of the causal relationship specied by a theory, a researcher should use”
- A limitation of the shotgun approach to identify variables that correlate with a criterion variable is that
- “Multiple regression, path analysis, hierarchical linear modeling, and structural equation modeling are similar in that all of them”
- The size of a research sample
- A scattergram provides a visual representation of
- In research investigating relationships between variables, it is best if
- A major advantage of correlational research designs over causal- comparative research designs is that
