Praxis 5003 Practice Test Practice Question
For the preceding list, which of the following statistics has the greatest value?
Correct Answer: D
Rationale: The range represents the difference between the highest and lowest values in a dataset, capturing the overall spread. This often results in a larger numerical value compared to the mean, median, or mode, which focus on central tendencies rather than spread.
The mean averages the values, which can be skewed by outliers. The median, the middle value, can also be less than the range, especially in datasets with extreme values. The mode, the most frequently occurring value, may not reflect the dataset's extent and can be lower than the range. Thus, the range typically has the greatest value among these statistics.
