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.
What is the difference between the population and sample regression functions? Is this a distinction without difference?
random sample is a big sample and convenience sample is small sample

A sample is any subset of the total population. A representative sample is one that is chosen so that its characteristics are similar to that of the population.
The main difference is that the way of selecting a sample Random sample purely on randomly selected sample,in random sample every objective has a an equal chance to get into sample but it may follow heterogeneous,to over come this problem we can use stratified Random Sample Here the difference is that random sample may follow heterogeneity and Stratified follows homogeneity
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
A sample survey is asked of a limited group of people, while a census is conducted in an attempted to get an answer from all people in a geographical area.
A census aims to collect data from an entire population, while a poll collects data from a sample of the population. A census provides a comprehensive and accurate snapshot of the entire population, while a poll offers insights based on a smaller subset.

sample is a noun and sampling is TO sample(verb)
random sample is a big sample and convenience sample is small sample
a sample is a sample sized piece given... a sample size is the amount given in one sample
A census is a statistical enumeration and analysis of a certain population, be it humans, animals or plants - groups that grow and change over time. A survey can be a tally of opinions or answers. See "Family Feud" when Richard Dawson says, "Survey says...!!!!"
Population is total number of people who live in a geographical area
A sample is a portion and a census measures absolutely everyone in the whole country. A representative sample measures a small number of people who fit a particular category of people: surveying 200 white male smokers between 20 and 40 who have had surgery for throat cancer (out of a total number of say 35,000 men who fit that profile).
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.
