Hi all,

I want to look at the effect of policy on the change in working hours for a certain age group. I have LFSdata split into quarters and I have managed to create pre and post policy variations of the variable I am looking at. However, I have more observations post policy than I do pre policy and so I have 100 or so missing data points. I have included a picture to give you an idea of what it looks like. I was wondering whether this would impact the values stata gives for descritpive statistics e.g. mean, standard deviation etc. Would it be adviseable to just ignore the 100 extra data points post policy and have equal sized groups?
