The entire population.
A census samples 100% of the population (ie it is not a sample, but the whole population) → the census will ask of 100,000,000 people.
It is the population.
It means you can take a measure of the variance of the sample and expect that result to be consistent for the entire population, and the sample is a valid representation for/of the population and does not influence that measure of the population.
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
Rarely or ever is the entire population questioned (if the population is small than you will come close sometimes). A sample (often over 1000) is the common practice.
Statistics: Survey of an entire population, as opposed to a sample survey.
A census aims to collect data from an entire population, while a survey gathers information from a sample of the population. Censuses are comprehensive and usually mandatory, whereas surveys are typically voluntary and sample-based. Censuses are used to provide official population counts and demographic data, while surveys are often conducted to gather specific information on a particular topic.
No. Only a census can ACCURATELY predict the outcomes: a random sample cannot.
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.
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.
A Census is the type of survey for a complete population. A Sample Survey is only a portion of the population which is used to make predictions on the representation of the actual population.
A census collects data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides a complete count and is more accurate, but requires more resources and time. A sample survey is faster and more cost-effective, but has a margin of error as it extrapolates findings from a smaller group to represent the larger population.
A population is the collection of all of the units of interest to a researcher. A sample is a subset of this collection that the researcher selects that is typically smaller than the population.
a census is the procedure of systematically acquiring and recording information about all d members of a given population and a sample is a group from d population a census is more thorough and gives accurate information about a population while being more expensive and comsuming time comsuing rather than a sample
No, it is not true. All that a sample gives you is an estimate about what the distribution might look like in the entire population. If you know what the distribution in the population looks like you have an error free fact and no estimate can better than that. another way to look at that: the bigger a sample gets the better the accuracy of the estimate. The sample cannot be bigger than the population however. The one caveat is in the data collection process. Under certain circumstances a sample may be more precise when data collection is difficult or flawed.
