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.
Information obtained from the sample can be extrapolated to the whole population using statistics.
A statistic and a sample have a relationship similar to that between a population and a parameter. A sample is a subset of a population, while a statistic is a numerical value calculated from that sample, used to estimate the corresponding population parameter. Essentially, a statistic provides insight into the characteristics of a larger group based on the analysis of a smaller, representative portion.
A sample is a subset of the population.
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.

From a sample of a population, the properties of the population can be inferred.
Information obtained from the sample can be extrapolated to the whole population using statistics.
The relations depend on what measures. The sample mean is an unbiased estimate for the population mean, with maximum likelihood. The sample maximum is a lower bound for the population maximum.

You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.
Data is neither sample nor population. Data are collected for attributes. These can be for a sample or a population.
It is not a sample. A sample must be a proper subset of the whole population.
