Conguration: 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. The options in the conguration string are
separated by spaces.
h: header cells will be created
DF: the degrees of freedom
T: the critical T-value
tXl: the lower bound of the condence interval
tXh: the upper bound of the condence interval
tXm: the midpoint of the condence interval
std: the standard deviation
Example:
ConfT2mean(0.461368, 0.522851, 0.2776, 0.2943, 50, 50, 0, 0.95, "")
Statistics 1Var app functions
The Statistics 1Var app has three functions designed to work together to calculate summary statistics based
on one of the statistical analyses (H1-H5) dened in the Symbolic view of the Statistics 1Var app.
Do1VStats
Do1-variable statistics. Performs the same calculations as tapping in the Numeric view of the
Statistics 1Var app and stores the results in the appropriate Statistics 1Var app results variables. Hn must be
one of the Statistics 1Var app Symbolic view variables H1-H5.
Do1VStats(Hn)
Example:
Do1VStats(H1) executes summary statistics for the currently dened H1 analysis.
SetFreq
Set frequency. Sets the frequency for one of the statistical analyses (H1-H5) dened in the Symbolic view of
the Statistics 1Var app. The frequency can be either one of the columns
D0-D9, or any positive integer. Hn
