Classes Command

Classes[ <List of Data L>, <Start S>, <Width of Classes w> ]

Gives a list of class boundaries. The first boundary (min) is equal to S, the last boundary (max) will be at least the maximum of L and the boundaries will be equally spaced between min and max.

Example: Classes[{0.1, 0.2, 0.4, 1.1}, 0, 1] gives {0, 1, 2}

Classes[ <List of Data L>, <Number of Classes n> ]

Gives a list of class boundaries. The first boundary (min) is equal to the minimum of L, the last boundary (max) will be the maximum of L and the boundaries will be equally spaced between min and max.

Example: Classes[{1, 3, 5, 7, 8, 9, 10}, 3] gives {1, 4, 7, 10}
