Suppose you wanted to know the average income in Canada but for your own convenience you decided to ask for income information from people who lived in cities and towns with airports so that you could fly to your destinations. The people in places like these often have higher incomes and would not form a representative sample of the people of Canada. In order to obtain a good estimate of average income you would need to find a way of ensuring that people of all income levels would have known probabilities of appearing in your sample.

If you want to have a scientifically valid sample for a study you are doing conditions must be met Check all that apply.?
To achieve a scientifically valid sample for a study, conditions that must be met include ensuring that the sample is representative of the population being studied, selecting participants randomly to minimize bias, and using an appropriate sample size to ensure statistical power. Additionally, it is important to control for confounding variables that could affect the results.
When there is as likely a chance that any one member of the population will be selected for participation in a study the sample is considered?
When there is an equal chance for each member of the population to be selected for participation in a study, the sample is considered to be a random sample. This method helps ensure that the sample is representative of the population, reducing bias and allowing for more generalizable results. Random sampling is a fundamental principle in statistical research techniques.
If you want to have a scientifically valid sample for a study you are doing?
To achieve a scientifically valid sample for your study, ensure that your sample is representative of the population you are investigating. This can be done through random sampling methods, which help eliminate bias and improve generalizability. Additionally, determine an appropriate sample size using statistical power analysis to ensure that your findings are reliable. Finally, consider stratifying your sample to account for key demographic variables that may influence the results.
What are the preliminary steps in statistical study?
The preliminary step is to research the issue and form your hypothesis. Then, you need to find your sample group.
What is a sample study?
sample is the population we make our study about them.
Why is a voluntary response sample not suitable for a statistical study?
Voluntary response sample is not generally suitable for statistical study because its results are not likely to be the representative of the entire population under study.Such results could be biased as those who made effort to respond voluntary have strong feelings or opinions whether favorable or unfavorable regarding the subject of consideration.

Are the results from Alisha's study anecdotal or do they apply to the general population?
To determine if the results from Alisha's study are anecdotal or applicable to the general population, we need to assess the study's methodology. If the study involved a small, non-representative sample and relied heavily on personal experiences, the findings may be considered anecdotal. However, if the study utilized a larger, randomized sample and robust statistical analyses, the results could be more generalizable. Ultimately, the study's design and sample size are critical in establishing its relevance to the broader population.
What three factors can a researcher can control when designing a valid study?
A researcher can control the sample size to ensure it is adequate for statistical power, thereby enhancing the study's reliability. They can also control the selection of participants to minimize biases, ensuring a representative sample. Additionally, the design of the study itself, such as choosing between qualitative or quantitative methods and establishing clear variables, can be managed to establish internal validity.
What is the purpose of randomization in epidemiology studies?
ensure taht the sample for the study is representative of the target population
What are the preliminary steps in statistical study?
The preliminary step is to research the issue and form your hypothesis. Then, you need to find your sample group.
Why is it important for a sample must be homogeneous?
It is important for a sample to be homogeneous to ensure that the results obtained from the analysis are representative of the entire population. Homogeneous samples reduce the risk of bias and help to improve the validity and reliability of the study findings. This ensures that any conclusions drawn from the sample are more likely to be accurate and applicable to the broader population.
Why is it important to study mapeh subject?

) Inherited traits are described by probabilities. When experimenting on inherited traits why is it important to have a large sample size?
A large sample size is crucial in experiments on inherited traits because it increases the reliability and accuracy of the results. With more individuals, the effects of random variation and anomalies are minimized, allowing for clearer observations of genetic patterns and probabilities. This helps ensure that the findings are representative of the population and reduces the likelihood of misleading conclusions. Ultimately, a larger sample size enhances the statistical power of the study.
