If one can represent the whole group?

I have qualitative drug susceptibility data (either "resistant" or "sensitive") for a set of bacterial strains for 6 drugs of the same class - i want to know if one of these drugs could represent the whole group. Which statistical method should be used to analyse this?


Less is more. Stay pure. Stay poor.
Can you provide a snippet of your data (fictitious or not), so we can better understand what you are writing about.

Thank you.
