What is the relationship between the problem statement and the research design?
Sample design and research design are two closely related concepts in research methodology, and the two are often interdependent. Research design refers to the overall plan or strategy for conducting research, including the selection of research methods, data collection procedures, and data analysis techniques. The research design is typically determined by the research question and the purpose of the study. Sample design, on the other hand, refers to the process of selecting a sample from a larger population for research or data analysis. The sample is a subset of the population that is selected to represent the population's characteristics accurately. The sample design is determined by the research question, the research design, and the population's characteristics. The relationship between sample design and research design is that the sample design is a critical component of the research design. The research design determines the overall approach to the study, while the sample design determines the specific subset of the population that will be studied. The research design guides the selection of research methods, data collection procedures, and data analysis techniques, while the sample design determines the size of the sample, the sampling method, and the criteria for inclusion in the sample. The sample design must be aligned with the research design to ensure that the sample represents the population's characteristics accurately and that the results are valid and reliable. Therefore, sample design and research design are interdependent and must be carefully considered when conducting research to ensure that the results are meaningful and accurate.
What is the difference between quota and stratified sampling?
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
What is targeted sampling in research studies?
I would like to sample the signal Xa(t) =1+cos(10 *pi*t) using sampling frequency fs=8 Hz. How can I calculate this? ANSWER: Your signal has a frequency component of 5hz (from the equation: 2*pi*f*t = 10*pi*t, therefore f=5). The Nyquist rate for this signal (the minimum sampling rate required to reconstruct the signal) is then 10Hz, and even at that rate the amplitude of the sampled signal will be reduced unless you can somehow synchronize the sampling with the peaks/troughs of the cosine signal. If you sample at 8Hz you will not be able to reconstruct the signal at all.
A scientific poll uses what kind of sample techniques?
Random sampling techniques.
Why unit of analysis is an integral part of research design?
The unit of analysis is an important issue to be considered to find the right answers to the research questions posed. The unit of analysis also determines the sample size. For example, if one is interested in researching the factors that influence the stock market in three different European countries, it is the behavior of stock markets in those three countries that are of central interest to the study, and not the individual stock market within each country. At the time of data analysis, the data gathered from each of the stock markets within each country will somehow have to be meaningfully aggregated, and only those three data points, which will form the three samples, have to be taken into consideration. Thus, the unit of analysis is a function of the research question posed, and is an integral part of the research design. As will be seen later, research design decisions relating to sampling also depend on the unit of analysis. Let us say a researcher decides to have a sample size of 30 for a study. Sampling 30 individuals in an organization when the unit of analysis is individuals, is not as problematic as sampling 30 organizations when the unit of analysis is organizations, or sampling 30 countries when the unit of analysis is countries. Thus, the unit of analysis influences other decisions such as the sampling design, the sample size, data collection methods, etc.

What do you mean by sample design?
Sample design refers to the process of selecting a sample from a larger population for research or data analysis. The sample is a subset of the population, which is selected to represent the population's characteristics accurately. Sample design involves determining the size of the sample, the sampling method, and the criteria for inclusion in the sample. The size of the sample is typically determined based on the desired level of precision, level of confidence, and resources available for the research or data analysis. The sampling method can be random, stratified, cluster, or systematic, depending on the research question and the characteristics of the population. The criteria for inclusion in the sample are determined by the research question and the population's characteristics. For example, if the research question is about the prevalence of a particular disease in a population, the sample design may include criteria for age, gender, and other demographic variables to ensure that the sample represents the population's characteristics accurately. Sample design is a critical aspect of research and data analysis, as it directly affects the accuracy and generalizability of the results. A well-designed sample can help to minimize bias and increase the reliability of the results, while a poorly designed sample can lead to inaccurate or misleading conclusions. Therefore, it is essential to carefully consider sample design when conducting research or data analysis to ensure that the results are valid and reliable.
What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
What is a population in research?
The popo ulation in the people/items you have collected data from. if you are sampling, the its the population of which you select your sample from
What difference between Statistical Sampling and non statistical sampling?
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
What is primary sampling?
Primary sampling is a research method used by various companies for many different reasons. The primary sampling unit arises in sampling surveys where population elements are grouped, and those groups becomes units in the sample selection.
What is a criterion based sample?
A criterion-based sample is a non-probability sampling method where participants are selected based on specific characteristics or criteria relevant to the research study. This approach ensures that the sample reflects particular traits that align with the research objectives, enhancing the relevance and validity of the findings. It is commonly used in qualitative research, where the focus is on understanding a particular phenomenon or group rather than generalizing to a larger population.
A ramdonly-selected group that is used to represent a whole population?
A sample is a randomly-selected group chosen to represent a larger population for research or analysis. Sampling aims to provide insight into the characteristics and behaviors of the entire population based on the traits observed in the sample. It is an essential method in statistics and research to draw conclusions about a larger group based on a subset of its members.

What type of sampling (sample strategy) is it when I am sampling employees from different organizations?
Convenience sampling or quota sampling
What is a sampling universe?
A sampling universe is what a sample is intended to represent.
What is the meaning of purposive sampling?
The sample mean helps researchers maintain the scope of their research. If the sample mean is too far from the mean of the population then the numbers may be skewed.
