Data Weighting

One of my clients approached me the other day and asked me: 

‘Look I’m running this survey and realize that I’m not getting enough young males in my sample. For whatever reason, they’re not responding as much as they should. I only have limited resources and time to find these respondents so I have to cut off the fieldwork time now. This means that I’m going to be left with too few males in that category. Can data waiting help me with that?’ 

I explained to him yes, that is exactly what data weighting is for. When you know that you have a mismatch in your sample, and you know what the compensation should be. You can apply data weighting to correct those biases in your sample.
