Error Type Possible Causes and Suggested Remedies
SINGULARITY expression in the Equation Solver contains a
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.
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 data points in
each partition.
• When you use a frequency list, its elements
must be 0.
• (Xmax-Xmin)/Xscl must be 47 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. See the appropriate chapter.
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 c after Med-Med.
