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.
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 sentence is a true statement Is a sample a subset of the population or Is a population a subset of the sample?

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.
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.
Why inferential statistics is not required in census?
Inferential statistical methods are used when data is collected from a sample in the population. Inferential statistics are used to generalize the results of the sample to the population. In a census you have data from each and every member of the population, so you just use descriptive statistics.
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.
What are the four methods for collecting research data?
The four main methods for collecting research data are surveys/questionnaires, interviews, observations, and experiments. Each method has its own strengths and weaknesses, and researchers may choose the most appropriate method based on their research questions and objectives.
