Parameters are a. numerical characteristics of a population b. the averages taken from a sample c. numerical characteristics of a sample d. numerical characteristics of either a sample or a population
Accepted Solution
A:
Answer:a. numerical characteristics of a populationStep-by-step explanation:Parameters and StatisticsIt's important to mention that there is a difference between parameters and statistics. A statistic is a numerical value of a variable that is part of a sample of the population. We have for example the sample mean [tex]\bar X[/tex] or the sample standard deviation s as examples of statistics.A parameter is a value who represent a numerical characteristic of a population. We have for example the population mean [tex]\mu[/tex] or the population standard deviation [tex]\sigma[/tex] as examples of parameters.Based on this the best answer would be:a. numerical characteristics of a population
