HypT2mean The hypothesis test HypT2mean is a two-sample T-test for
comparing means.
HypT2mean(input list, ["configuration"])
HypT2mean(SampMean1,
SampMean2,SampStdDev1,
SampStdDev2,SampSize1, SampSize2, pooled,
SigLevel, Mode, ["configuration"])
• Input List: A list of input variables (see Input Parameters
below). This can be a range reference, a list of cell
references, or a simple list of values.
• Input Parameters:
–
SampMean1
– SampMean2
– SampStdDev1
– SampStdDev2
– SampSize1
– SampSize2
– pooled = 0 == false or 1 == true
– SigLevel
• Mode: Specifies how to calculate the statistic:
–
1 = Less than
– 2 = Greater than
– 3 = Not equal
• Configuration: A string that controls what results are
shown and the order in which they appear. An empty
string "" displays the default: all results (including
headers).
–
h = header cells will be created
– acc = Accept/Reject
– tT
– tM
– prob
– df
