Quizplus · Accepted Answer

Range measures the difference between the highest and lowest value in a dataset, while standard deviation and variance measure the spread of data around the mean. Together, these three tools provide a comprehensive assessment of variability in a dataset. Mean, median, and mode, along with skewness, are measures of central tendency and do not provide information about variability.
