Question.3362 - Using the reading and video this week: Define what a sample is Write about how a sample is supposed to relate to a population Discuss problems with samples. Define sampling error Then, using the information in your text: Identify what the GSS sample size is What does the text say the GSS sampling error is? Why is it important we know the sampling error for the GSS sample?
Answer Below:
Define what a sample is According to the video in the module (5.7 Sampling Error | Quantitative Methods | Sampling | UvA, n.d.), a sample is a subset of individuals, objects, or data obtained from a large group called a population. Write about how a sample is supposed to relate to a population A sample is representative of the population and should reflect all its population characteristics so that the conclusions drawn from the sample can be applied to the entire population. Discuss problems with samples. The problem with samples is bias. If the sample is not randomly selected, it does not reflect the entire population's opinion. Also, if the chosen individuals in the sample do not respond, it can create gaps in the data. Define sampling error Sampling error is the difference between the sample estimate and the true population parameter due to random sampling. The sample results would be different from those obtained from the survey of the entire population. Identify what the GSS sample size is The GSS sample size is 2348 ( Babbie et al., 2015). The value entered is from GSS2018. What does the text say the GSS sampling error is? The GSS sampling error is roughly estimated as -/+ 2%. Instead of saying that precisely 50% of the total adult population supports a woman's unrestricted right to an abortion, sampling error roughly estimates that 48% to 52% of the total adult population supports a woman's unrestricted right to an abortion ( Babbie et al., 2015). Why is it important we know the sampling error for the GSS sample? Knowing the GSS sample's sampling error is important because it provides a range within which population parameters are likely to fall. A smaller sampling error indicates a more precise estimate.
