Answer:
A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample
Step-by-step explanation:
In statistics we have to deal with populations and samples to carry out our studies. A population is a large group under consideration and the elements or members of the population have some common features or attributes. For example, all the school going kids in a certain town will be considered a population. Sample on the other hand is a subset(a part) of the population. For example, all school going kids in the town aged 5-6 years will be considered a sample.
The term Parameter and Statistic are very similar as they represent some numeric description. Parameter represents the data of the entire population, while statistic represents that data of a sample. An easy way to remember this is to match the initials i.e. Parameter for Population and Statistic for Sample.
Considering this, we can say the correct answer is:
A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample
