TTest

[Anonymous]

Hello,

Who knows how works TTest in Qlikview?

I have variables A and MYear in Dimension. Avg(Var2) in expression.

Variable	MYear	Jan 2012	Feb 2012	Mar 2012	Apr 2012	May 2012	Jun 2012	Jul 2012	Aug 2012	Sep 2012	Oct 2012	Nov 2012	Dec 2012	Jan 2013
A		7.2	7.4	9.4	7.5	5.8	8.8	8.7	6.3	8.8	8.7	9.1	8.1	9.3
B		6.7	6.9	6.9	6.9	7.4	7.0	7.3	7.2	7.5	6.8	7.0	6.6	7.3
C		4.5	6.6	8.1	6.7	6.0	7.1	6.8	6.3	6.0	7.0	8.7	6.2	7.5
D		6.7	6.9	6.6	6.4	6.6	6.9	6.7	7.0	6.9	6.8	6.7	6.7	7.0
E		6.4	6.5	6.3	6.7	6.8	6.8	6.6	6.9	7.0	6.2	6.7	6.4	6.6
F		6.5	6.3	6.4	6.3	6.5	6.5	6.6	6.6	6.7	6.1	6.5	6.4	6.6

I want to know, if I have significance changes from month to month.

TTest_sig ([set_expression][ total [<fld {,fld}>] group, value [,eq_var = true])

Thanks,

I don't use QV tools. I don't know how to set up parameters.
