The Census Bureau classifies towns in Massachusetts as a type of "minor civil division" and cities as a type of "populated place". However, from the perspective of Massachusetts law, politics, and geography, cities and towns are the same type of municipal unit, differing primarily in their form of government and some state laws which set ...
On July 21, 2023, the OMB delineated two combined statistical area, seven metropolitan statistical areas, and three micropolitan statistical area in Massachusetts. [1] As of 2023, the largest of these is the Boston-Worcester-Providence, MA-RI-NH CSA , comprising the area around Massachusetts' capital and largest city of Boston .
For example, each of the three populations {0, 0, 14, 14}, {0, 6, 8, 14} and {6, 6, 8, 8} has a mean of 7. Their standard deviations are 7, 5, and 1, respectively. The third population has a much smaller standard deviation than the other two because its values are all close to 7. These standard deviations have the same units as the data points ...

For an approximately normal data set, the values within one standard deviation of the mean account for about 68% of the set; while within two standard deviations account for about 95%; and within three standard deviations account for about 99.7%. Shown percentages are rounded theoretical probabilities intended only to approximate the empirical ...
About 68% of values drawn from a normal distribution are within one standard deviation σ from the mean; about 95% of the values lie within two standard deviations; and about 99.7% are within three standard deviations. [8] This fact is known as the 68–95–99.7 (empirical) rule, or the 3-sigma rule.
Positive deviations (above the mean) and negative deviations (below the mean) are included in the calculation. The mean signed deviation provides a measure of the average distance and direction of data points from the mean, offering insights into the overall trend and distribution of the data. [3]
