Preparation
For this research, you will use the archival data from the grades.sav to develop a research question, develop a hypothesis, and analyze the data to draw conclusions.
Make sure you have downloaded the SPSS data set titled grades.sav and saved the file locally on your computer’s hard drive.
Instructions
In the next assessment, you will start to conduct your research study. We conduct research studies to expand our knowledge on how human behavior in the world is evolving. To conduct an effective study, we need to understand theories of development as they relate to our current environment and society.
The first step, however, is to create a research proposal that provides the detailed plan for your study. Be sure to use the Research Proposal Template [DOCX], as it provides context and wording that you should use to help you clearly explain your main points. By using the template, you will cover all of the points below.
Insert your revised literature review in the Literature Review section in the template.
Operationally define the variables that you are using in your study.
State your hypothesis for your study.
Report on the method you will use to sample your participants.
What type of sampling strategy would using archival data be considered? To help answer this question you may want to view the different sampling terminology from Trochim (2006).
Use your notes from the media piece to guide your sampling method selection.
Explain the method you will use to collect and analyze your data.
What specific, inferential statistic is the appropriate statistic to use for your study based on the scale of measurement of your variables? To help answer that question, view Privitera (2018).
Use your notes from the media piece to guide your sampling method selection.
Choose the measurement that matches your study.
Review the template for suggested language.
Discuss how the measurement increases the reliability and validity of the study.
Explain your procedure based on research design you chose.
