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
Zero
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 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.
a sample is a sample sized piece given... a sample size is the amount given in one sample
Population is total number of people who live in a geographical area
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.
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 random sample is better than a census because it takes less time and costs less.
