Similarity and difference sample and population, census survey and sampling, parameter and statistic, data and variable.

Answer 1

Sample and population:
- Similarity: Both are used in statistical research and analysis.
- Difference: A population refers to the entire group of individuals, objects, or events that researchers are interested in studying, whereas a sample is a subset of the population that is chosen to represent the larger group.

Census survey and sampling:
- Similarity: Both are used to gather information and data from a group of individuals or objects.
- Difference: A census survey collects information from every member of a population, while sampling is a process of selecting a subset of individuals or objects from a larger population to gather data.

Parameter and statistic:
- Similarity: Both are used in statistical analysis.
- Difference: A parameter is a characteristic or measure derived from the entire population, while a statistic is a characteristic or measure calculated from the data obtained from a sample.

Data and variable:
- Similarity: Both are used in statistical analysis and research.
- Difference: Data refers to the information collected or observed in a study, while a variable is a characteristic or attribute that can differ or have different values within a population or sample. Variables are used to represent and measure the data collected.
