Predict what will happen to the coordinates of a point (x, y) as the point rotates counterclockwise (CCW) about the origin to produce point (x’, y’). Choose rotation angles of 90°, 180°, 270°, and 360°. Express your answers in terms of x and y. Be sure to watch your signs.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
