Complete Question:
Determine whether the given value is a statistic or a parameter. A sample of 818 adults showed that 39% voted in the past election. Choose the correct answer below.
A. The value is a parameter because it is a numerical measurement describing some characteristic of a parameter sample.
B. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic population.
C. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.
D. The value is a parameter because it is a numerical measurement describing some characteristic of a parameter population.
Answer:
C. The value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.
Explanation:
If a sample of 818 adults showed that 39% voted in the past election. Therefore, the value is a statistic because it is a numerical measurement describing some characteristic of a statistic sample.
In Statistics, a sample can be defined as a set of data (individuals, observations or objects) collected from a larger statistical population using specific procedures. Therefore, a sample is a subset or part of population.
The difference between a statistic and a parameter is that; statistic is a numerical measurement describing some characteristic of a statistic sample while parameter is a numerical measurement describing some characteristic of a population.
In this scenario, a sample of 818 adults from the total population showed that 39% voted in the past election. The data collected represents a sample and as such, it is a statistic value.
