Correlation coefficient ti 84.
The viewing rectangle on the TI-83 is 94 pixels by 62 pixels. (A pixel is a picture element.) It is useful when graphing to have a “friendly window” in order to avoid distortion in the graph and to avoid obtaining non-integer values when using the trace function of the TI-83. In fact, q ® (ZoomStat) usually gives a "friendly window".
