Texas Instruments TI-84 Plus Calculator User Manual


 
Appendix B: General Information 175
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 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. Appendix A displays the arguments and
punctuation needed to execute the function or
instruction.
For example,
stdDev(list[,freqlist]) is a function of the
TI-84 Plus. 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.
TOL 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 handheld is not authorized to run the
application.
