Discussion Overview

The discussion revolves around the correctness of a 2 x 3 factorial ANOVA chart related to a study on speech errors. Participants are examining the data presentation and the calculations involved in the ANOVA analysis, focusing on the interaction between distraction and speech difficulty.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Meta-discussion

Main Points Raised

  • Ryan presents a summary table of a 2 x 3 factorial ANOVA and seeks feedback on its correctness.
  • Some participants suggest that the format of the data could be improved for clarity, specifically by using a table format.
  • There is a concern about ensuring that all components of the ANOVA table, particularly the degrees of freedom, are correctly calculated and add up properly.
  • Participants express confusion regarding the visibility of images and suggest alternative methods for presenting the data.

Areas of Agreement / Disagreement

Participants generally agree that the presentation of the data needs improvement for clarity, but there is no consensus on the correctness of the ANOVA chart itself as the discussion is still ongoing.

Contextual Notes

There are unresolved issues regarding the visibility of images and the format of the data presentation, which may affect the ability to assess the ANOVA chart accurately.

Have I completed this 2 x 3 factorial ANOVA chart correctly?

A sample of ¬N = 36 is recruited to participate in a study about speech errors. The researchers believe that there is an interaction between whether the speaker is distracted (distracted or not distracted) and the difficulty of the speech they’re asked to present (low, medium, or high) on the number of speech errors. They hypothesize that the participants who are distracted who have a high difficulty speech will make the most errors. The data from this experiment were examined using a 2 x 3 factorial ANOVA. The results are presented in the following summary table.

Source SS df MS F

Between Treat. 39.2 5
Factor A 11.2 1 11.2 Fa = 4.00
Factor B 20 2 10 Fb = 5
AxB 8 2 4 Faxb = 2
Within Treat. 84 30 2.8
Total 123.2 35Thanks in advance for your help,

Ryan

I apologize for the format.

Hi there. Can you try putting this info into a table? That will make it easier for us to read. Click on this button. View attachment 3576

With ANOVA tables it's all about making sure everything adds up, especially the degrees of freedom. I'll do my best to look it over when it's readable. :)

Unfortunately, I am unable to view your picture. Also, I am not able to upload a .docx file either.

That's weird that you can't see my picture. Are you using a phone or tablet maybe?

Anyway, click the first button on the fourth row all the way to the left. It looks grid like.

Here is an example of a table.

[table="width: 500, class:grid"]
[tr]
[td]A[/td]
[td]B[/td]
[/tr]
[tr]
[td]C[/td]
[td]D[/td]
[/tr]
[/table]
 
Jameson, perhaps the OP assumed there was an image to view by clicking the image you posted.

MWR, Jameson is referring to the following button on our toolbar:

Click that button and it will allow you to define a table for presenting your data. :D
