Which of the following is a statistic?
- A Selecting 10 employees from an organisation with 100 employees
- B Selecting 10 students from a class and finding their mean height to represent average class height
- C Finding mean income of all families in a city
- D Finding median income of all families in a city
Answer & Solution
Correct Answer
(B) Selecting 10 students from a class and finding their mean height to represent average class height
Step-by-step Solution
Detailed explanation
A statistic is a value calculated from a sample, not the whole population.Option B uses 10 students (a sample) to find the mean height, so it is a statistic.Options C and D use all families (entire population), so they are parameters, not statistics. (B)Selecting 10 students…
