What does Fse test for simple effects tests?
Step by step
Solved in 3 steps
- A simple main effect test is appropriate for analyzing which significant result?When looking at your residual analysis and seeing all of the desirable graphs demonstrate a strong correlation between your independent and dependent variables, is this enough evidence to say that your independent variable makes a good predictor for your dependent variable? If yes, state why. If no, explain what other factors you need to consider.How does the F-statistic change if one sample is very different from the others?
- What is the Predicted calculation? What is the residual?What are the requirements for an experiment to be able to show that changes in one variable cause changes in another?Compute the value of the correlation coefficient between time spend for studyingand current CGPA and describe the relationship.
- Analyze the residuals from this experiment and comment on model adequacy.Report the value of the correlation coefficient.How does the answer to this question differ from the method used to find the difference of variability for the same data? (At the 0.05 level of significance, is there evidence of a difference in the variability of the computer anxiety experienced by males and females?) vs. (is there evidence of a significant difference in the average computer anxiety experienced by males and females.) Are both of these questions answered the same way, using the same formulas and method?
- Initial data from a sample of 100 people suggests that stress increases blood pressure (a positive correlation is observed). What is the null hypothesis?What steps do I take on SPSS to do data screening for a T-Test?Is it possible to use STATcrunch to find the linear correlation coefficient instead of the formula?
