The tables in this section describe the inferential statistics inputs discussed in
this chapter. You enter values for these inputs in the inferential stat editors.
The tables present the inputs in the same order that they appear in this
chapter.
Input Description
m0Hypothesized value of the population mean that you are
testing.
sThe known population standard deviation; must be a real
number > 0.
List The name of the list containing the data you are testing.
Freq The name of the list containin
g
the frequency values for the
data in List. Default=1. All elements must be integers | 0.
Calculate/Draw Determines the type of output to
g
enerate for tests and
intervals. Calculate displays the output on the home screen.
In tests, Draw draws a graph of the results.
v, Sx, nSummary statistics
(
mean, standard deviation, and sample
size) for the one-sample tests and intervals.
s1The known population standard deviation from the first
population for the two-sample tests and intervals. Must be
a real number > 0.
s2The known population standard deviation from the second
population for the two-sample tests and intervals. Must be
a real number > 0.
List1, List2 The names of the lists containin
g
the data you are testin
g
for the two-sample tests and intervals. Defaults are L1 and
L2, respectively.
Freq1, Freq2 The names of the lists containin
g
the frequencies for the
data in List1 and List2 for the two-sample tests and
intervals. Defaults=1. All elements must be integers | 0.
v1, Sx1,
n
1, v2,
Sx2,
n
2Summary statistics
(
mean, standard deviation, and sample
size
)
for sample one and sample two in the two-sample
tests and intervals.
Pooled Specifies whether variances are to be pooled for
2.SampTTest and 2.SampTInt. No instructs the TI.83 not to
pool the variances. Yes instructs the TI.83 to pool the
v
ariances.
