Which one of the following is a statistic?a. the range of a populationb. the median of a populationc. the average of a populationd. the mean of a sample
A statistic is a numerical value that is derived from a sample or a population and is used to describe or summarize certain characteristics of the data
A statistic is a numerical value that is derived from a sample or a population and is used to describe or summarize certain characteristics of the data.
Out of the four options you provided, three of them (range, median, and average) are measures that can be applied to a population. However, the range is not considered a statistic, but rather a descriptive measure that shows the spread or variability of a dataset. The range is calculated by subtracting the smallest value from the largest value in a dataset.
On the other hand, both the median and the average (also known as the mean) are statistics that can be calculated for a population. The median is the middle value in an ordered dataset, while the average or mean is the sum of all values divided by the total number of values.
Therefore, the correct answer to your question is:
b. the median of a population
