Four HIT students are working on a LOS project at their clinical site. To describe the variability of the data, Smithson suggests using range because it is the most exact; Donaldson wants to use the mean because it is easy to calculate; Franklin recommends variance because it is the most popular measure of variability; and Howell proposes the use of standard deviation because it is the most easily understood. Who made the best suggestion?

Question

Quizplus · Accepted Answer

Standard deviation is the most commonly used measure of variability as it provides a clear indication of how much the data deviates from the mean. It also allows for easy comparison of variability between different sets of data, making it a practical choice for statistical analysis. Additionally, it is often used in inferential statistics, which are frequently employed in healthcare research.
