Which of the following are measures of spread or dispersion? mean range median standard deviation mode interquartile range

## Step 1: Understanding Measures of Spread<br />### Measures of spread describe how spread out the data is. They quantify the variability of the data points. Measures of central tendency, on the other hand, describe the center of the data.<br /><br />## Step 2: Identifying Measures of Spread from the List<br />### Range: The difference between the maximum and minimum values. This clearly measures spread.<br />### Standard Deviation: A measure of how spread out the data is from the mean. A higher standard deviation indicates greater spread.<br />### Interquartile Range: The range of the middle 50% of the data. This is another measure of spread.<br />### Mean, Median, and Mode are measures of central tendency, not spread.
