Why is a sample often used instead of a census?
because its faster and then when you use a sample you can easily make accurate predictions about what would/will happen next
Why is a random sample better than a census?
A random sample is better than a census because it takes less time and costs less.
When do we sample when collecting data?
You can sample when carrying out a comprehensive census is not feasible for any reason. It may be because a census would require too many resources (including time), be destructive (eg life span of light bulbs).
What is the difference between census and sample investigation?
this is brief, but a census gathers data from the whole group/poulation, wheras a sample investigation on takes a small part of the group/poulation, a sample

Less time and less cost for a sample.

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 a sample and a census?
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.
How does a census compare to a sample?
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
Why is sample survey better than a census?
becuase it is more accurate.
What are the differences between census and sample survey?
A census aims to collect data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides accurate and precise information for the entire population, while a sample survey estimates characteristics of the population based on the sample. A census can be time-consuming and costly, while a sample survey is more practical for large populations and can still provide valuable insights with less resources.
What is census in statistics?
Statistics: Survey of an entire population, as opposed to a sample survey.
Is a census a collection of data based on a sample or the entire population?
The entire population.
Why is sampling preferred over census?
Less time and less cost for a sample
What would you use to find out the amount of people in a given area?
A census
What is total population survey?
It would be something like a census, surveying every last person in a given population rather than taking a random sample.
Will Random sample always accurately predict the outcomes of an entire population?
No. Only a census can ACCURATELY predict the outcomes: a random sample cannot.
