Solution 34421: Drawing the X-chart or R-bar Graphs Using the TI-84 Plus C Silver Edition Graphing Calculator.
Will the TI-84 Plus C Silver Edition draw an X-Chart or R-Bar Graph?
X-Chart and R-Bar graphs are another way of representing sample data.The r-bar chart takes the ranges of the observed measurements and plots it with the upper and lower control limits. R-Bar graphs the mean of the samples with the upper and lower control limits. This allows any out of control conditions to be observed.
The TI-84 Plus C Silver Edition does not have a built in feature that creates and displays x-Chart or R-Bar graphs. There may be third-party programs available on the Internet that may add this functionality. An example search would be "TI-84 Plus +R-Bar graph".
