Good morning from Portugal! I´m a biologist and I use SPSS for my statistical analysis.
I have some categorical data from questionnaires and made a chi-square analysis (most of the data had assumptions violated, so I used Fisher´s Exact test instead) followed by Phi or Cramer´s V to analyse the strength of association. My question is ... and then what? I know two variables are associated, I know if it is a strong or weak association, but I would like to know which category from the variable is really making the difference (sorry if I can´t explain correctly).
I´ll give an example:
I tested if respondents age were related to what they know about an invasive species - it is, and is a strong association. How do I know which of the age classes knows better the species?
Most of my tables are nxn. I send a crosstab in the attachment.
Thanks in advance!
