What is represenatative sample of population?
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
What are Pros and Cons of population and sample in statistics?
1
What is the difference between population survey and sample survey?
A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
What type of statistics employ the use of sample data that is used to infer information about the population?
Inferential statistics.
What is represenatative sample of population?
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
What is the relationship between sample and population?
From a sample of a population, the properties of the population can be inferred.
What is the difference between population and sample in statistics?
A population includes all members of a defined group. A sample, on the other hand, is just a part of the population.
How is a linear relationship between two variables measured in statistics?
The Correlation Coefficient computed from the sample data measures the strength and direction of a linear relationship between two variables. The symbol for the sample correlation coefficient is r. The symbol for the population correlation is p (Greek letter rho).
What is the difference between target population and sample population?
the sampled population includes all people whom are included in the sample, the targeted population is what the statistics practitioner is targeting or questioning
What is a subset from a larger population?
in statistics a sample is a subset of population..
What are examples of the relationship between descriptive and inferential statistics?
Descriptive statistics summarize and present data, while inferential statistics use sample data to make conclusions about a population. For example, mean and standard deviation are descriptive statistics that describe a dataset, while a t-test is an inferential statistic used to compare means of two groups and make inferences about the population.
What is census in statistics?
Statistics: Survey of an entire population, as opposed to a sample survey.
What are the statistical methods called that use sample data to answer general questions about a population?
Inferential statistics. This branch of statistics involves making inferences or predictions about a population based on data collected from a sample taken from that population.
What are Pros and Cons of population and sample in statistics?

What is population mean in statistics?
The population mean is the mean value of the entire population. Contrast this with sample mean, which is the mean value of a sample of the population.
When can statistics be used to gain information about a population from a sample?
When the sample - whether it is random or systematic - is somehow representative of the population.
