[R] One-way ANOVA with replicates

[Senaka Amarakeerthi]

Hi All,
I have a dataset (attached) with three groups (treatments) namely Neutral ,
Video, Audio and four output variables.
I am planning to check the ANOVA results to show that is a difference in
observations when treatment is changed.
To generalize the conclusion, I did the same experiment for set of people
(subjects in attached file).
Now I am not sure whether I can use One-Way ANOVA for my dataset. Highly
appreciate if somebody can explain me.
I am using the R package to analyze data.
Thank you.
