Explanation:

• Parameter: A parameter is a characteristic of a population. The number of eligible voters who actually plan to vote in the whole community (related to the population of all eligible voters) is a parameter. So, the number of eligible voters who actually plan to vote corresponds to the parameter.
• Sample: A sample is a subset of the population. A group of voters in the community who voted, randomly - selected, is a sample.
• Variable: A variable is a characteristic that can take on different values for different elements in the sample or population. The attendance of a single voter can vary (present or absent), so it is a variable.
• Data: Data are the values that the variables take. "Voted, didn't vote, voted" are data values related to the voting variable.
• Statistic: A statistic is a characteristic of a sample. The number of eligible voters in the study (sample) who actually plan to vote is a statistic.
• Population: The population is the entire group of interest. All eligible voters in the community is the population.
