Thanks for the reply!!

I do not have a model yet and I am mainly asking about statistical tests that have an assumption of independent samples and if my population violates the assumption of independent samples (I understand there are dependent and independent variables).

So, imagine there are 100 homes affected by a Wildland fire. They are organized in groups of two adjacent homes, so fifty groups, lets say. Let’s say all groups had at least one destroyed home, some had two destroyed homes. Let’s say all groups that had one destroyed home had water suppression on that destroyed home, and all groups that had two destroyed homes had no water suppression on any of the homes. Let’s say we determined unequivocally that surviving homes where dependent on water suppression on the adjacent destroyed home.

If the above is the case, then are the destroyed and surviving homes not independent samples and this population violates the assumption of independent samples for statistical tests that have that assumption.

Obviously sometimes it is easier than others to determine if samples are independent of each other and I am trying to determine what is the case for this hypothetical sample.

Thanks!
