Question One

It is not unusual for researchers to use a convenience sample for their study. For example, if you would like to see if there is a correlation between the time parents spend working with their children on home work and the children’s school grades, you may consider recruiting your friends and relatives to participate in your study because it will be easier to obtain their permission for data collection. What might be some of the limitations of this sampling approach? 

Question Two

What is the difference between a population and a sample? How large do you think your population and sample will need to be for your dissertation research? Explain your reasoning. What factors other than size will you consider in relation to sampling? Why? What types of descriptive statistics will you consider for summarizing the sample? Why?
