Question

The best way to gain understanding of a sampling and estimation method is to carry it out on some real population of interest to you. Choose a human target population and a population parameter of interest (for example, a mean, a proportion or a total). Suppose you are interested in planning a sample survey and you establish a questionnaire regarding your variable of interest.

Clearly state your objective. Define your target population. Find a suitable sampling frame. Describe your sample design.

Describe three potential sources of error in questionary design that you would address in order to minimize the bias.

Answer 1

The best way to gain understanding of a population parameters one needs to sampling and obtain sample estimates. Now according to our objective the target population should be chosen and shoild selectedrandomly in order to remove any kind of bias in the estimates. Also the sampling error can be minimize if taken care at each and every step of the sampling technique.

the three potential source of error in questionary design tht would lead to bias in the estimates are as follows:

1. response error: sometimes the question isn't clear to the respondent hence leads to an absard responses.

2. the ordering of the question, and

3. respondent notgiving the full proof answers to the questions because of recall bias.
