Typically, a sample survey consists of the following steps:
- Define the target population.
- Select the sampling scheme and sample size.
- Develop the questionnaire.
- Recruit and train the field investigators.
- Obtain information as per the questionnaire.
- Scrutinize the information gathered.
- Analyze and interpret the information.
Subsequently, question is, what are the types of survey methods? The span of time needed to complete the survey brings us to the two different types of surveys: cross-sectional and longitudinal.
- Cross-Sectional Surveys. Collecting information from the respondents at a single period in time uses the cross-sectional type of survey.
- Longitudinal Surveys.
Likewise, what are the 4 types of sampling methods?
There are four main types of probability sample.
- Simple random sampling. In a simple random sample, every member of the population has an equal chance of being selected.
- Systematic sampling.
- Stratified sampling.
- Cluster sampling.
What are the basic principles of a sample survey?
Three basic principles for the design of a sample survey are: 1. Principle of Optimization The principle of optimization takes into account the factors of (a) Efficiency and (b) cost. (a) Efficiency Efficiency is measured by the inverse of sampling variance of the estimator.
