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.
Are the sample mean and sample proportion of a population are called population parameters?
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.
Statistic and a sample is the same relationship between what?
A statistic and a sample have a relationship similar to that between a population and a parameter. A sample is a subset of a population, while a statistic is a numerical value calculated from that sample, used to estimate the corresponding population parameter. Essentially, a statistic provides insight into the characteristics of a larger group based on the analysis of a smaller, representative portion.
What are Pros and Cons of population and sample in statistics?

Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
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.
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
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).
Are the sample mean and sample proportion of a population are called population parameters?
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.
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.
