TTest2( <List of Sample Data 1>, <List of Sample Data 2>, <Tail>, <Boolean Pooled> )
Performs a t-test of the difference between two population means using the given lists of sample data. Tail has possible values "<", ">" , "≠" that determine the following alternative hypotheses:
"<" = difference in population means < 0
">" = difference in population means > 0
"≠" = difference in population means ≠ 0
If Pooled = true, then population variances are assumed equal and sample standard deviations are combined in calculation.
If Pooled = false, then population variances are not assumed equal and sample standard deviations are not combined.
Results are returned in list form as {Probabilty value, t-test statistic}.
TTest2( <Sample Mean 1>, <Sample Standard Deviation 1>, <Sample Size 1>, <Sample Mean 2>, <Sample Standard Deviation 2>, <Sample Size 2>, <Tail>, <Boolean Pooled> )
Performs a t-test of the difference between two population means using the given sample statistics. Tail and Pooled are defined as above. Results are returned in list form as {Probabilty value, t-test statistic}.
