ScaleTrans
should meet specific demands in the psychological practice and in the
psychological research and offers with its extensive functionality ideal
tools for users and developers of psychodiagnostic scales.
| |
|
 |
ScaleTrans
supports both linear and area transformations. As a special case
of area transformations, percentiles are treated particularly
comfortable. |
|
| |
|
In
addition, ScaleTrans features the transformation based on areas
of arbitrary empirical distributions into all scale types and
vice versa. The empirical data can be imported from most statistical
packages and table calculation programs as for example MS Excel,
Minitab, SAS, SPSS or Statistica. Particularly optimized algorithms
are applied for discrete and continuous distributions in each
case. Thus ScaleTrans makes possible problem-free and methodically
correct handling of anomalous-distributed scales. |
|
| |
|
ScaleTrans
makes possible the comfortable, accurate and fast conversion of
separate values of any scale into all other scales. You only choose
the reference scale and the reference value is transformed immediately
into all available scale equivalents. Besides, the whole output
can be copied at any time and be inserted in any table calculation
or word processing application. |
|
| |
|
ScaleTrans
visualizes the value and accumulated area of the reference value
in a normal distribution. The size of the graphic can individually
be adapted proportionally or unproportionally; farther the graphic
can be copied, stored and be inserted in any text or image processing
application. This function is particularly useful with the creation
of diagnostic findings or reports. |
|
| |
|
ScaleTrans
already pre-defined the most usual scales for you, so that you
can start your work immediately in most cases. |
|
| |
|
ScaleTrans
is at pleasure extendable for hundreds of user-defined scales
for which all functions of predefined scales are available. The
production of own scales is structured clearly and requires no
profound knowledge. Besides, predefined scales can serve as a
basis for new, user-defined scales what essentially simplifies
the process in a lot of cases. |
|
| |
|
ScaleTrans
comes with an integrated probability calculator for arbitrary
normal distributions. |
|
|
- |
Parameters
of already created (user-) defined linear scales can be used. |
|
| |
- |
Both
the area computations on the basis of a value (CDF-function; integration)
and the valuation on the basis an area (inverse function) are
supported. |
|
| |
- |
In
addition, special options permit right-cumulated and two-tailed
computations and inverted scales (e.g. school grades). |
|
| |
- |
The
probability calculator has its own (hideable) visualization, which
illustrates the values and the integrated areas intuitively. In
addition this relieves not only the understanding of the computations,
but also avoids misunderstandings with the interpretation of the
results. |
|
| |
- |
This
graphic can also be copied, stored and be inserted in any text
or picture processing application. This function is particularly
useful with the creation of diagnostic findings or reports or
to illustrate the relations to nonprofessional persons. |
|
| |
|
|
ScaleTrans
revolutionizes the creation of conversion tables: Within seconds
enormous conversion tables (with up to 1.000 scales and 100.000
lines) can be created upon the basis of any (also empirical and
user-defined) reference scale. These tables can be problem-free
inserted into statistic-, spreadsheet analysis or text processing
applications (e.g. MS-Word, MS-Excel, Minitab, SAS, SPSS or Statistica)
for further processing. |
|
| |
|
ScaleTrans
supports the export of all user-defined scales. Therefore you
can hand on selected scales to other users or make, for example,
all scales of your questionnaire available for your customers
in the world-wide internet. Your customers will be able to work
with the Lite-Version of ScaleTrans and your scales even in commercial
contexts free of any charge. |
|
| |
|
ScaleTrans
allows the export of all user-defined scales in a text format
readable for the user. In this way you can put together all specifications
of all of your scales within a few seconds. The further processing
of the scale information for example in a text processing application
(e.g. MS-Word) is fast and simply realizable. |
|
| |
|
Of
course ScaleTrans also supports the import of previously exported
scales. You can select the scales to be imported comfortably.
With the import the correctness of the imported data is checked
constantly, so that potential damaged data is tracked down. |
|
| |
|
You
may distribute the Lite-Version of ScaleTrans, for example, on
a diskette together with your scales and therefore make possible
to your customers the conversion of the raw values of your scales
to all predefined standard scales by the click on a button. Read
the next section to find out more. |

Farther
ScaleTrans has an extensive program help system which supports you when
working with the program.
The
functionality of the unlicensed full version of ScaleTrans is limited.
