G-Power and SPSS
To what extent does age, race, and gender predict the annual salary of bank presidents?
Conduct an a-priori analysis, a medium effect size, and alpha of .05 and a power of .80. What is the sample size you need to prevent a type II error? What is a type error, and how does an adequate sample prevent it? Show your work by providing your G*Power output.
Problem 2:
What is the difference in growth rate between publicly traded enterprises and privately held firms?
Conduct a post hoc analysis with a sample size of 100, a medium effect size, and an alpha of .01, what is the power of your study? Explain what the post-hoc power means. Show your work by providing your G*Power output.
Sample Solution
A Priori Analysis − This is all about the theoretical analysis of an algorithm. theWhere efficiency of an algorithm is measured by assuming that all other factors, for example, processor speed, are constant and have no effect on the implementation.A Posterior Analysis − This is more of an empirical analysis of an algorithm. The selected algorithm is implemented using programming language and then executed on target computer machine. In this analysis, actual statistics like running time and space required, are collected.
