Title: OA 3 Graphing
Course: PSYC 301 Statistical Methods in Psychol > Section: First Part of Course

For this assignment, you will submit a Microsoft Word file. It will involve exporting individual pieces of information from jamovi and pasting them into Word, along with some written responses from you.

For this exercise you need to download the linked data file (OA3Data.omv) and open it in jamovi.

We are imagining we have preliminary data from 4 sites around the nation at which creativity is being measured in individuals on a 0 to 100 scale. We need to produce a preliminary report for our sponsor showing that we have some data successfully collected and what it looks like. We have learned that being scrupulously honest is always best in these circumstances, so even though we know our data is incomplete, that's how we will report it.

Follow these steps:

1. Once open in jamovi, click on Exploration, then Descriptives.
2. In the analysis box select Creativity variable and move it to the Variables box and select Data Site and put it in the Split by box.
3. Select Std. Deviation as a measure also. Note also that it's under a heading called 'Dispersion' which is another word for the several ways to measure variability.
4. Open up the Plots portion and select Histogram.

This will give you graphs.

Then follow these steps:

1. Click on Data Site in the Split by box and remove it (click the left pointing arrow next to the box)
2. We are going to act like we learned the site of Seattle had an error in calculating the creativity scores from the measuring system and it is best that the Seattle data be removed from our report. Do the following:
  1. Select the Data tab.
  2. Select the Filters option.
  3. click on the little f_x symbol under Filter 1.
  4. Double-click the variable Data Site. It should appear in the box above like this: 'Data Site'
  5. Click your cursor after the single quote for Data Site and type: != (exclamation point followed by an equals sign). Just like == means 'equals' for filtering, != means 'not equals' for filtering.
  6. Type exactly this: 'Seattle' (including the single quotes. Do NOT use regular quotes.)
  7. Click anywhere on screen.
3. Note how you now have a single histogram and a single set of descriptive calculations (this is a histogram of all the data but Seattle's data removed)

You now need to export the histogram to insert into a Word document. Do these steps:

1. Hold down the control key while clicking on the last histogram you had jamovi make. A pop up menu will appear.
2. Select Image, then Copy. On your virtual clipboard is a copy of the image file.
3. Open Word either on Word 365 (part of your email) or on the local computer you are using.
4. Select from the Edit menu the Paste command.
5. The histogram should appear in the document. Resize it to be smaller by clicking on the image and click-and-drag one of the handles.

In that same Word Document, describe the advantage (as you see it) to eliminating the values from a single site compared to seeing the data from each site and trying to pull it together. I am not looking for a 'proper correct answer' here. I merely want you to think about these two different ways of getting at subsets of the data and the relative versatility and value of each. A sentence or two is plenty.

Keep it very short and sweet. Miniprojects are for more involved writing.

Submit that Word Document as your submission for this assignment.
