Page 114: Steps For Defining A Stat Plot
Chapter 6: Statistical Plots Steps for Defining a Stat Plot Follow these basic steps when defining a statistical plot. You may not have to do all of them each time you graph the designated lists. Define numerical and categorical lists in the List editor. Deselect Y functions, if desired.
Page 115: Defining Statistical Data In Lists
Chapter 6: Statistical Plots Defining Statistical Data in Lists Statistical plots (stat plots) are graphical representations of data that has been stored in lists. Therefore, since you need to create your lists before you can define stat plots, review Chapter 5: Lists for information on naming and creating both numerical and categorical lists.

Appendix B: Reference Information The VARS Menu - } Access system variables through the menu (- }). VARS You can enter the names of functions and system variables in an expression or store values to them directly. For more information about storing values to a variable, see Chapter 1: Operating the TIN73.
Page 336: Equation Operating System (Eos É)
Appendix B: Reference Information Equation Operating System (EOS é) The Equation Operating System (EOS) defines the order in which functions and expressions are entered and evaluated on the TIN73. Within a priority level, EOS evaluates functions from left to right and in the following order. Calculations within parentheses.

Page 338: Correcting An Error
Appendix B: Reference Information Correcting an Error When the TIN73 detects an error, it returns an error message as a menu title, such as ERR:SYNTAX ERR:DIM MISMATCH To correct an error, follow these steps: Note the error type ( :error type). Select , if it is available.
Page 339 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies A function or instruction does not have the correct ARGUMENT number of arguments. See Appendix A and the appropriate chapter. You specified a guess in the Equation Solver that is BAD GUESS not between the lower and upper bounds.
Page 340 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies You attempted to divide by 0. This error is not DIVIDE BY 0 returned during graphing. The TIN73 allows for undefined values on a graph. You attempted a linear regression with a vertical line.
Page 341 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies You attempted to use an invalid function in an ILLEGAL NEST argument to a function, such as within seq( expression for seq( Can occur when combinations of nesting of function evaluation exceeds five levels.
Page 342 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies Memory is insufficient to perform the instruction or MEMORY function. You must delete items from memory (Chapter 13: Memory Management) before executing the instruction or function. Recursive problems return this error; for example, graphing the equation Y1=Y1 Branching out of an...
Page 343 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies expression in the Equation Solver contains a SINGULARITY singularity (a point at which the function is not defined). Examine a graph of the function. If the equation has a solution, change the bounds or the initial guess or both.
Page 344 Appendix B: Reference Information Error Type Possible Causes and Suggested Remedies A problem exists with the variables. WINDOW WINDOW RANGE • You defined Xmax Xmin Ymax Ymin • variables are too small or too large to WINDOW graph correctly. You may have attempted to zoom in or zoom out to a point that exceeds the TIN73’s numerical range.
