Data that has a symmetrical, bell‐shaped distribution where the mean, median, and mode are identical.
A frequency distribution.
A bell-shaped curve that graphically rep¬ resents statistical data called norms, such as test scores; an ideal form that tends to result when large numbers of data are depicted on a graph. This form, like an upturned tulip-shaped bowl, with most scores falling in the middle and many fewer scores at the top and bottom ranges, is also used by teachers in grading ON the curve. A curve that does not have the standard shape but instead has scores clustered at either the high or low end of the graph is called a skewed distribution.
In statistics, the theoretical, smooth, continuous, symmetrical bell-shaped curve made by tallying the frequency distribution of random data points. The mean, median, and mode of the data coincide.
