Yes, I am. Include rooms. It depends on how you are going to analyze the data.
Re: hazard opportunity. I don’t know anything about this topic beyond just lived experiences. I don’t know what’s on your hazards list but let’s say extension cords. So, plausibly, an extension cord laying on the floor where people walk is a hazard. So, suppose I tape it down. Still a hazard? Maybe. Harder to trip on but still possible. But it’s also been at least partly remediated.

Gene: thanks. Are you suggesting beside a total hazards variable that I include a number of rooms variable. It is possible then that the total number of hazards might be highly correlated with the number of rooms. And are you saying that a hazard is a hazard (unremediated hazard opportunity). martin

Martin,
I addition to what others have said, I think that you might want to consider multiple ways of working with the data. Certainly compute the mean, hazards per room. I don’t know that weighting is the correct concept here because weighting seems to be part of the design of a complex survey design. I think it might be useful to investigate total hazards as a function of number of rooms. I wonder if the relationship is linear. I could imagine that it’s not because number of rooms probably has some correlation magnitude with wealth/income, which might well be related to hazard opportunity. Depending on how you asked the questions, a hazard is an unremediated hazard opportunity.

Subject: How to code hazards across house rooms
Dear List: I have just received an SPSS data file from a colleague that contains responses from a City’s elderly residents who reported on safety hazards within their homes/apartments. Each room could have anywhere from 10 to 14 hazards that the residents had to check off. We are interested in getting a total hazards score for the five rooms (across the kitchen, living room, bedroom, dining room, and bathroom). However, I have noticed that not all of the residents had five rooms. Some lived in efficiency apartments and only had two rooms. If I totaled up the number of hazards across all rooms those with fewer rooms would automatically have lower hazards. If I obtained the mean across all of the rooms than residents could have the same mean number of hazards but it would be based upon a different number of rooms. I am trying to figure out how to factor in the number of rooms. Some way of weighting the scores but I am a bit dumbfounded on this. I realize that this is not an SPSS question but would appreciate suggestions (if you would like to chime in) as I begin to figure out how to analyze the data. Thanks in advance, martin
