ERROR TYPE Possible Causes and Suggested Remedies
SINGULARITY expression in the solve( function or the equation solver
contains a singularity (apoint 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.
STAT You attempted a stat calculation with lists that are not
appropriate.
Statistical analyses must have at least two data points.
Med-Med must have at least three points in each partition.
When you use a frequency list, its elements must be 0.
(Xmax N Xmin) à Xscl must be between 0 and 131 for a
histogram.
STAT PLOT You attempted to display a graph when a stat plot that
uses an undefined list is turned on.
SYNTAX The command contains a syntax error. Look for misplaced
functions, arguments, parentheses, or commas.
For example, stdDev(list[,freqlist]) is a function of the
TI-84PlusCE. The arguments are shown in italics. The
arguments in brackets are optional and you need not type
them. You must also be sure to separate multiple
arguments with a comma (,). For example stdDev(list
[,freqlist]) might be entered as stdDev(L1) or stdDev(L1,L2)
since the frequency list or freqlist is optional.
TOLERANCE
NOT MET
You requested a tolerance to which the algorithm cannot
return an accurate result.
UNDEFINED You referenced a variable that is not currently defined. For
example, you referenced a stat variable when there is no
current calculation because a list has been edited, or you
referenced a variable when the variable is not valid for the
current calculation, such as a after Med-Med.
VALIDATION Electrical interference caused a link to fail or this graphing
calculator is not authorized to run the application.
VARIABLE You have tried to archive a variable that cannot be archived
or you have tried to unarchive an application or group.
Examples of variables that cannot be archived include:
Real numbers LRESID, R, T, X, Y, Theta, Statistic variables
under Vars, STATISTICS menu, Yvars, and the AppIdList.
VERSION You have attempted to receive an incompatible variable
version from another graphing calculator.
A program may contain commands not supported in the OS
version on your graphing calculator. Always use the latest
