Hi All,

I hope someone can help me with this. I am trying to analyse time-series data. I have three data collection points pre-intervention and three post-intervention. What is the best way to analyse this data? Is it by doing a within and between group ANOVA. I read somewhere that in order to have sufficient data for regression, one has to have 20 data collection points pre intervention.

Thanks!!!
