Overview
A social work intern is conducting a parenting class for clients at her agency. The social work intern is interested in examining if there is a relationship between participants’ level of education (measured by how many years of schooling completed) and participants’ training posttest scores.
The student ran a Pearson’s correlation to address the research question. The intern's data file is attached. Focus on the relevant variables: “Level of Education” and “Posttest skill scores”.
For this homework, do the following:
- State your research question
- State your independent and dependent variables
- State your research hypothesis
- State your null hypothesis
- Conduct a Pearson's correlation in JASP with the intern data. Here is how to do it (details are in this week's PowerPoints):
- Create a spreadsheet with the intern data so that you can run it in JASP
- Save your file as .csv
- If using JASP online: Upload file to OSF
- Open your file in JASP: Open > My Computer > [Your file]
- If using JASP online: Open > OSF > Log in to OSF > [Your file]
- Double check that the variables are measured at the correct levels
- Run descriptives
- Run a graph
- Run your Pearson's correlation
- Interpret output; be sure to report:
- Your descriptives output table
- Write one - two sentences describing each of the variables
- Your graphs
- Your Pearson's correlation test output table
- Write an explanation of your Pearson's correlation test results in sentence form. Use this format, and fill in the information in red based on your results:
- I ran a Pearson's correlation test in JASP to examine [insert a brief explanation of what you were trying to understand]. I set the alpha level to ___. Results show that there was/was not a [if applicable: small/medium/strong] [if applicable: positive/negative] significant ______ between education and posttest scores, where p=___, r = ____. Therefore, I reject/do not reject the null hypothesis. In summary, [in simple terms, what does this mean about relationship between the variables?]
