What is a sample study?
sample is the population we make our study about them.
What is the purpose of using measures of central tendency and dispersion?
Given that the study manager wants the QC efforts to be focused on selecting outlier values, whose method is a better way of selecting the sample
What effect does non-random sample have on what you can say about the results of a study?
It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
Does the size of a sample affect the values of the frequency table?
Yes. If the sample is a random drawing from the population, then as the size increases, the relative frequency of each interval from the sample should be a better estimate of the relative frequency in the population. Now, in practical terms, increasing a small sample will have a larger effect than increasing a large sample. For example, increasing a sample from 10 to 100 will have a larger effect than increasing a sample from 1000 to 10,000. The one exception to this, that I can think of, is if the focus of the study is on a very rare occurrence.
Why was it important to Mendel to study such a large sample of pea plants to determine the probability of inheritance?
Answer D- A higher sample size gives more accurate results- APEX LEARNING

What is Haphazard selection?
Haphazard Selection is procedure of selecting a sample of individuals to study by taking whoever is available or happens to be first on a list.

Given that the study manager wants the QC efforts to be focused on selecting outlier values, whose method is a better way of selecting the sample
Is the subset of the population chosen by the investigator for a study?
The subset of the population chosen by the investigator for a study is known as the sample. Sampling involves selecting a smaller group of individuals from a larger population to make inferences or generalizations about the broader population. The goal is for the sample to be representative of the population so that findings from the study can be applied more broadly.
An experiment involves selecting a random sample of 256 middle managers for study One item of interest is annual income The sample mean is computed to be 35420 and the sample standard deviation is 205?
The deviation would be how much off it would be off. Since this is a sample, it is impossible to get completely accurate results.
What is a sample of a population that has been selected using a pattern?
A sample of a population that has been selected using a pattern is when a researcher selects every 10th person from a list or sampling frame. For example, if a researcher wants to study the attitudes of employees in a large company, they may select every 10th employee from the company directory. This method ensures a systematic pattern in selecting the sample.
What is selection in sociology?
Selection in sociology refers to the process by which individuals or groups are chosen for inclusion in a study or analysis based on specific criteria. It involves selecting a representative sample to study a particular social phenomenon or behavior, ensuring that the chosen sample is reflective of the larger population being studied. This process helps researchers generalize their findings and draw meaningful conclusions about society as a whole.

Whats a sample of something used in a lab for study or analysis?
A common sample used in a lab for study or analysis is water. Researchers use water in experiments to study its properties, measure contaminants, or test the effectiveness of treatment processes. It is a versatile sample because of its abundance and importance in various scientific fields.
What is the minimum respondents of descriptive study?
There is no specific minimum number of respondents for a descriptive study. The sample size in a descriptive study should be large enough to provide a meaningful representation of the population being studied, but there is no fixed minimum requirement. The size of the sample will depend on the research objectives, the variability of the population, and the desired level of precision.
What is sample survey?
A sample survey is a research method where a subset of a larger population is chosen to gather information or insights about the entire population. This process involves selecting a representative group to minimize bias and ensure the results can be generalized to the larger population. Sample surveys are commonly used in market research, social sciences, and public opinion polling.
A study in which researchers measure or observe characteristics of the sample members?
observational study
