I used to own a polling company with my wife Tracy Costin
The people that sponser the survey's are always asking for more then is realisticly possible
they will be making changes to survey questions right up to the last minute
then they want a certain number of responsise you can only cal a certain number of people in a certain geographic area
once use use up all your numbers and you can't get anyone else to answer questions what do you do?
plus they are always in a hurry you have to complete the survey in a very short time.
you can only call between certain hours.
it's really a high pressure biz
you get a lot of serveys that are incomplete
it's really frustrating
a little cut and pate of partial srveys can go a long way
you don't have to make up data just good old cut and paste
