What is the meaning of sampling frame?
A sampling frame is a list or database that includes all the elements in the population from which a sample will be drawn. It serves as a practical representation of the target population, ensuring that every member has a chance to be selected. An accurate sampling frame is crucial for conducting valid and reliable research, as it helps minimize bias and improves the generalizability of the results.
If you want to have a scientifically valid sample for a study you are doing conditions must be met?
To ensure a scientifically valid sample for your study, you must first define your target population clearly and use random sampling methods to select participants, minimizing bias. Additionally, the sample size should be sufficiently large to provide statistical power and representativeness. It's also essential to ensure that the sample reflects the diversity of the population in relevant characteristics, such as age, gender, and socioeconomic status, to enhance generalizability of the findings.
What should you take into considersation when selecting a sample for study?
When selecting a sample for a study, consider the target population to ensure it accurately represents the characteristics you want to investigate. Additionally, think about the sample size, as a larger sample can improve the reliability and validity of the results. It's also essential to consider sampling methods (random, stratified, etc.) to minimize bias and ensure that the sample reflects the diversity of the population. Lastly, ethical considerations, such as informed consent and confidentiality, should be taken into account.
How does size of target population affect sample size?
The size of the target population directly influences the required sample size for accurate representation and statistical validity. Larger populations generally require larger sample sizes to capture the diversity and variability within the population. However, after a certain point, increasing the population size has a diminishing effect on the required sample size, as the necessary sample size plateaus. This is due to the law of diminishing returns in sampling, where a sufficiently large sample can provide reliable estimates regardless of further population increases.
What sampling plan are used by penton media in inquiring minds want to know case study?
In the "Inquiring Minds Want to Know" case study by Penton Media, the sampling plan employed involved a combination of stratified and random sampling methods. This approach ensured that specific demographic segments were adequately represented while also allowing for the random selection of participants to minimize bias. By stratifying the sample, Penton Media aimed to capture diverse insights from various audience segments, enhancing the reliability and validity of the findings. Overall, the sampling strategy was designed to provide a comprehensive understanding of the target market's preferences and behaviors.
What is the third step in scientific polling?
The third step in scientific polling is to select a sample from the target population. This involves using a method, such as random sampling, to ensure that the selected individuals accurately represent the larger population. This step is crucial for minimizing bias and enhancing the reliability of the poll results. Proper sampling ensures that the findings can be generalized to the broader population.

What are the disadvantages for random sampling?
its time consuming and expensive if its a large sample you need or a big target population

Why do you use Stratified sampling?
They have used Stratified Sample. Design because stratified sample is a sampling technique in which the researcher divided the entire target population into different subgroups, or strata, and then randomly selects the final subjects proportionally from the different strata. This type of sampling is used when the researcher wants to highlight specific subgroups within the population. So in this Research this technique is used by the researcher.
What are the Advantage and disadvantage of purposive sampling?
Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.
What are steps in statistical survey?
The steps in a statistical survey typically include defining the research objectives, identifying the target population, and designing the survey instrument (e.g., questionnaires). Next, a sampling method is chosen to select a representative sample from the population. The survey is then administered, and data is collected. Finally, the data is analyzed, and results are interpreted to draw conclusions that address the research objectives.
What is circular systematic sampling?
Circular systematic sampling is a random sampling method. An example is random sampling of households. Assume that a random number generator provides the number 49 as a starting point. Starting with the household that is 49 on the target list, every nth household on the list would be sampled until the desired sample size is reached
What is the importance of sampling?
The importance of sampling is that you can determine the adequate respondents from the total number of target population. Thus, it will be used in the research study which should be adequate to warrant generalization of the findings to the target population. And the sample size represents the characteristics of the whole population (representativeness of the sample). The advantages of sampling are: it is economical and practical; faster and cheaper; it can yield more comprehensive information; it is more accurate; and because of savings it permits in time and money, the sample survey makes possible the use of much larger and much more varied populations than would be possible for the same expenditure if one were making a complete enumeration.
