Answer 1

Population: The population is collection of all individuals which are included in the study.

Sample: A representative part of population which is used to study about the population.

Parameter: Parameter are the values or measures which summarize the data of whole population.

Statistic: Statistics are the estimate of the parameter obtained from the sample data.

Here we have a sample of 500 registered voters in which 55% supports candidate A, 43% supports candidate B and 2% supports “other”. Now we can observe that these percentages are obtained from the sample of 500 registered voters and we know that the any information obtained from the sample is known as statistics.

Hence the correct option is D. Statistics.
