It is possible to base a study on observations as well.
But I agree that the questionaire needs to be targetting to both genders in order that the sample data contains enough male and female climber to compare against. While there are in general less women climbers than men, you need to compare men progressing from rock into winter against women progressing from rock into winter to be able to make any real analysis.
If you question 50 women climbers and 20% of them progress into winter - what does that mean in relation to everyone else? it might be only 20% of men progress into winter as well but as there is a larger male population in rock climbing (only in my observations) then there would be a larger population of male winter climbers.
