My study is about the effect of an oral repetition activity on oral fluency.
So oral fluency is the dependent variable and it is a continuous variable measured by the number of words (is it a ratio variable though?)
The repetition activity is the independent variable and has 3 subgroups (students who did no repetition, students who did a total of 10-19 times of repetition and students who did a total of 20-29 times). I'm not sure which type of variable this is ... Is it also continuous (ratio) or an ordinal variable? Or another type?
Age is an independent variable. Speaking activities does not come under variables. But oral fluency under each task will come under dependent variable.
Independent variable does not get influenced by other factors, but dependent variable usually gets influenced by other factors.
Hi there,
It may not be the BEST answer; however, I will try to provide you with my suggestion. I hope it will help.
- First, the number of words, which is your DV, can be in either ratio or nominal variable. For example, if you have criteria that rated the subject like high, moderate, or low level of oral fluency due to the number of words, then the DV can be noted as nominal variables.
- Second, the repetition activity which has three subgroups, I will mark it as nominal variables, instead of ratio variables. As in my point of view, IV is the main interest of your study, that what kind of repetition activity will affect the subject to produce more words. The comparison between the subgroups might provide more meaningful information, or else you have more interest in scatter plots to see the correlations/trends between the repetition activity and the number of words in your study. So what kind of variables do you DV can be, it depends on your research interest.
