If a researcher has collected data by using Google form and got the data from different universities which is scattered in the country , how can he/she state the demographic structure of the sample and what type of sampling procedure he/she will use?
If a researcher has collected data using a Google form from different universities scattered across the country, they can state the demographic structure of the sample by analyzing the data collected to determine various demographic characteristics present in the sample. This could include variables such as age, gender, ethnicity, education, and other relevant demographic characteristics.
In terms of what sampling procedure to use, there are various options available, including simple random sampling, stratified sampling, cluster sampling, and multi-stage cluster sampling. The choice of sampling procedure will depend on factors such as the size and characteristics of the population, the resources available, and the research objectives.
If the researcher wants to ensure that the sample is representative of the population, they may want to consider using a stratified sampling procedure where the population is divided into distinct subgroups or strata based on key demographic variables, and a random sample is then drawn from each stratum. Alternatively, if a list of all universities in the country is available, the researcher could use systematic sampling by selecting every nth university from the list to ensure that the sample is representative of the population.
