Which term refers to how spread out values are around the mean?

The term that describes how spread out values are around the mean is standard deviation. Standard deviation quantifies the amount of variation or dispersion in a set of data values. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range. This measure is crucial in statistics as it helps in understanding the distribution of data points in relation to the average, thus providing insights into the reliability and variability of the data.

Other terms mentioned, such as Venn diagram, probability, and range, serve different functions. A Venn diagram is a visual tool used to represent relationships between different sets. Probability pertains to measuring the likelihood of an event occurring, while range describes the difference between the highest and lowest values in a data set. However, none of these terms specifically address the concept of dispersion around the mean in the same way that standard deviation does.
