The tool makes it relatively easy
to get started. Everything is controlled from a single
window that follows the analogy of an open Filofax,
with two open pages for you to work on centre-screen
and tabbed dividers left and right indicating the other
program options. This is both convenient and efficient
during the set-up stages, as you can drag and drop from
one side to the other. Different pages allow you to
choose the study you want to work on, the questions
to go in the rows, the columns, filters and so on.
The product is a cross-tab tool, not
a data mining or multivariate analytical tool, and it
contains a wealth of options for setting up tables.
You can define filters, group answers, combine and recode
questions and put any number of items on the top, down
the side or into the level - the third dimension
of the tables.
When you are ready, a run button generates
the table and the display changes from personal organiser
to something that looks disarmingly like Microsoft Excel.
Indeed, it behaves very much like Excel in terms of
applying stylistic changes. You can change the type
size, font, colour, apply formatting rules, paste in
graphics - but you just cant change the numbers.
You can also post the table to Excel proper, if the
fairly standard range of presentation and charting options
in mTABS dont fulfil your needs. If you have applied
a variable such as month as a level, then
a workbook of tabbed worksheets will be presented, each
one relating to a separate month. It is easy to add
an overall total sheet too.
Stepping through tabbed sheets like
this makes year on year comparisons easy, and it is
one of many thoughtful features for continuous research.
An important one is its ability to join together different
databases. A tracker could be delivered as a different
database for each year, yet you could analyse it as
if it were one large database. When you open more than
one, you designate one to be the primary study.
All the variables are then colour coded: red for a total
mismatch, amber for slight differences you must resolve
and green for a perfect match. As products and company
names come and go, you can easily resolve those differences,
and take the decisions yourself how to do this.
It is all pretty powerful stuff.
Mean averages can be calculated on actual or midpoint
values, and you can vary these. There is excellent support
for hierarchical data through what are called grouped
variables, and you can flip between bases at one level
or another with ease. Definitions, filters and even
recodes can be saved, then reapplied later on the same
database or another one.
There is a good range of significance testing, but the
display was surprisingly crude: rather than converting
results into significance levels (e.g. 95%), all you
get is the raw standard deviation result. Furthermore,
a constraint of the single spreadsheet workbook for
output is that it only ever shows the current item you
are on. There is no gallery of output previously produced
as there is in, say, SPSS.
A rare MR customer is MORI,
which uses mTAB on its Financial Services Omnibus, both
in-house and to distribute databases to its subscribers.
Technical Support Manager John Cogswell comments: A
lot of our clients see the value of being able to go
along way beyond the basic cross tabs you can produce
on paper. And using this, we can enrich our omnibus
data with data from third parties, such as financial
or geodemographic data. We went for this for its ease
of use - it is incredibly user friendly with its
drag and drop interface, and the Excel framework, means
people feel they are familiar with it from the start.
Among his favourite features are the traffic-light recoding
of data between databases, and a feature called top
N. Essentially you sort the columns on a
table independently of each other. If you are trying
to highlight differences this has to be the easiest
way to use it.
MORI has been beta testing
a new Java version, due out later this year. Cogswell
approves of the move. It will give clients the
flexibility of accessing our data anywhere, and removes
from them the responsibility for installing databases
on their own network. Security procedures often mean
this can take a long time: having the data outside,
on the internet, can take that problem away.
