In basic statistics what is sample size and effective sample size?
sample size refers to the collection of data by only a selected size of te population through the process of sample surveys and sampling methods used in collecting data.
Portion of the population selected to represent the population is called Options statistical inference descriptive statistics a census a sample?
The portion of the population selected to represent the entire population is called a sample. A sample is used in research and statistics to draw conclusions about the larger population without needing to survey every individual. In contrast, a census involves collecting data from every member of the population, while statistical inference and descriptive statistics relate to methods of analyzing and interpreting data.
Methods of collecting information?
what are the two methods of collecting information
What is sample and population relationship?
The sample is a subset of the population. For example, the population may be all the people at your school. A sample might be 5 people from each class. There are different types of sampling methods. The most commonly used is a simple random sample. When your obtain data from the entire population this is called a census.
What techniques used to estimate something about a population based on a sample are called?
The techniques used to estimate characteristics of a population based on a sample are called statistical inference methods. These methods include point estimation, confidence intervals, and hypothesis testing. They allow researchers to draw conclusions about a population's parameters from the data collected in a smaller, representative sample. Common techniques involve using measures like the sample mean or proportion to infer about the population mean or proportion.

Why is sample importance?
sampling is important because it helps for researching and also collecting data from a population.

What are the similarities btn census and sample survey?
Both census and sample survey are methods used to collect data from a population. However, while a census attempts to gather information from every individual in the population, a sample survey collects data from a subset of the population. Both methods aim to provide insights and statistics about the population under study.
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.
If A Population Is A Sample Of The Population Could Be .tion could be .?
If a population is considered a sample of a larger population, it means that the characteristics and behaviors of that sample can be used to make inferences about the entire population. This approach is often employed in statistical analysis where studying the entire population is impractical. The sample should be representative to ensure that the findings are valid and reliable. Proper sampling methods help minimize bias and enhance the accuracy of conclusions drawn about the larger population.
How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
What is subset of a population called?
A Sample
Why are sample used in statistics?
Because a sample is information obtained from the population that will be used in hypothesis testing. WER 1.19.2011 Samples are used to save time and money when the population is large and when the units must be destroyed to gain information.
What is the difference between an extensive and intensive survey?
An extensive survey involves collecting data from a large and diverse sample population, providing a broad understanding of a topic. In contrast, an intensive survey focuses on collecting in-depth information from a smaller, more targeted sample, offering detailed insights into specific aspects of the topic.
