We consulted professors of scientific research from Humboldt State University and College of the Redwoods in order to determine how many completed surveys we needed in order to have confidence that the results accurately reflected the sentiments of 2nd District voters overall.
Based on these conversations, we determined we needed at least 300 completed surveys from a random sample of registered voters in the 2nd District. We used a pure random sampling technique, which is the most accurate form of probability sampling. This means that each member of the population has an equal and known chance of being selected.
There are 15,700 voters in the Second District, Local Solutions provided us a randomly generated list of 2,100 voters from this pool for us to call in order for us to reach our completed survey goal of 300.
Our final number of completed surveys was 312 registered voters, which represents approximately 2% of the registered voters in the Second District.
