Error Type Possible Causes and Suggested Remedies
SINGULARITY expression in the solve( function or the equation solver
contains a sin
g
ularity
(
a point at which the function is not
defined
)
. Examine a
g
raph of the function. If the equation
has a solution, chan
g
e the bounds or the initial
g
uess 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 47 for a histogram.
STAT PLOT You attempted to display a
g
raph when a stat plot that uses
an undefined list is turned on.
SYNTAX The command contains a syntax error. Look for misplaced
functions, ar
g
uments, parentheses, or commas. See
Appendix A and the appropriate chapter.
TOL NOT MET You requested a tolerance to which the al
g
orithm 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.
WINDOW RANGE A problem exists with the window variables.
¦You defined Xmax Xmin or Ymax Ymin.
¦You defined qmax qmin and qstep > 0 (or vice versa).
¦You attempted to define Tstep=0.
¦You defined Tmax Tmin and Tstep > 0 (or vice versa).
¦Window variables are too small or too lar

correctly. You may have attempted to zoom in or zoom
out to a point that exceeds the TI.83’s numerical range.
ZOOM ¦A point or a line, instead of a box, is defined in ZBox.
¦A ZOOM operation returned a math error.
