I am doing a true experimental report. I have one independent variable with 3 levels and 1 dependent variable. It is a between subjects design. So, is it 3x1? or 1x3? or is it 3x3? Please help, I am very confused and overthinking it.
Also, is one-way repeated ANOVA an appropriate inferential statistical test?
Is this a homework question, Rebecca Robinson? I ask, because you seem very confused about the terminology for basic ANOVA designs. Perhaps the material here will help:

Good luck.
Based on your description, it sounds like you have a one-factor between-subjects design with three levels of the independent variable and one dependent variable. Therefore, the design would be called a 3x1 design, with the "3" representing the three levels of the independent variable and the "1" representing the one dependent variable.
It is important to note that a 3x3 design would refer to a two-factor experimental design with three levels of two independent variables, which does not seem to be the case in your study.
In terms of what design you should use, a one-factor between-subjects design could be appropriate for investigating the effects of a single independent variable (with two or more levels) on a dependent variable. It is a common and straightforward design often used in experimental research.
You could refer to chapter 10 of the following textbook for insights.
