How useful is SPSS for a data analyst path? Can it help to increase his chance to get a job?


How useful is SPSS for a data analyst path? Can it help to increase his chance to get a job?

I think R and related open source programs have cut into SPSS’s market, but it is still a valuable program to learn. We use it at my university place of employment fairly often. This is for operational research, not strictly academic work, though obviously a lot of academic research is done via SPSS, especially in the social sciences.

In addition, A great deal of survey work is done in SPSS, whether you are doing your own surveys or doing secondary analysis on some other organization’s surveys. SPSS has a lot of features that are very useful for survey work, such as its multi-response capabilities (i.e. one of those survey items that says “check all that apply to you”).
SPSS also has many regression/ANOVA and other statistical modelling type procedures (also cluster analysis, factor analysis, etc.). The menu-driven system is very useful for doing analyses on the fly, or for pasting the code that the program creates into a script. You can then modify that code by hand, so to speak, using the voluminous documentation that exists on SPSS (including lots of user produced stuff on the web).
The SPSS packages that I have access to have some limited machine learning procedures. For deeper access to these algorithms you may need the SPSS data modeller product (that can run into pretty big bucks).
It is a bit awkward for data processing - often it is better to do those steps outside of SPSS via some SQL product, then import into SPSS.
So, knowing SPSS is certainly useful, especially in some employment areas. It is especially good within academia or for survey work in general, and as a more gentle introduction to statistical modelling than some other packages such as R or Python (less coding knowledge needed). And, the more packages you know, the more impressive your C.V. to a potential employer.

Now, you can forget about data science for a while, and have some fun reading:

Kati 1 - Escape from the Drowned Planet

Kati 1 - Escape from the Drowned Planet
Kati and Mikal's escape from the alien slaver Gorsh.

In saving her small son from alien abductors, a 24-year-old Earth woman, Katie, finds herself abducted instead. She awakens from a drug-induced coma on a spaceship, in a room full of children, both human and alien, and two other women, younger than she is. The young women adapt to the situation as best they can, keeping the youngsters calm and entertained. But, when a drugged alien man wearing a uniform is added to the captive cargo, it becomes clear that this is an intergalactic slave operation.

The slave traders implant their captives with “translation nodes” in order to allow communication among various groups. These are living entities, normally docile, merely enhancing certain brain functions, such as language acquisition. However, Katie discovers that she has accidentally received a very special “granda node”, a long-lived node with its own cantankerous personality, including a fondness for criminality and lethal weaponry. Fortunately for Katie, it also values its freedom. With its help, she escapes on a fringe planet, dragging the peace officer along—also at the granda’s suggestion.

She finds herself on a strange world, with a somewhat deranged personality, quite possibly a killer, in her head, and partnered with a man from an advanced civilization who abhors killing. He is a Federation Peace Officer, captured by the slavers while attempting to bring them to justice. His task is complicated by the fact that he has sworn to avoid the taking of sentient life during the performance of his duties. He can and does, however, make vigorous use of non-lethal weaponry. Since, before leaving the ship, Katie had promised to help her co-captives gain their liberty, she and the alien peace officer find that they have a common cause.
But first they must find their way off the primitive planet and get to the Federated Civilization, avoiding the slavers who have been left on the planet to re-capture them. Their flight is complicated by the fact that the planet has had a global warming catastrophe some centuries back – the locals refer to it as the Drowned World. This has forced the inhabitants to revert to a pre-industrial state of development; however, they are a wily and resourceful people, mostly helpful, but they can also be dangerous.

Kati (to mark her escape, she adopts a slight name change) and Mikal seek a Federation beacon, which had been hidden on this planet ages ago, to aid in situations such as this, (in accord with a longstanding Federation policy for fringe worlds). They must embark on an arduous trek across two continents and an ocean, seeking the temple that holds the beacon. They travel on foot, by cart, by riverboat, by tall sailing ship, and on pack animals, always pursued by the dangerous slavers.
They must rely on their wits, guile, charm and acting abilities to avoid recapture, while their chasers have advanced technology and ruthlessness on their side. Fortunately, they are able to make many friends who help them along the way, and their quest becomes a series of adventures, both frightening and funny, and involving a cast of engaging characters.

To complicate matters, Kati finds herself falling in love with Mikal, the strange, handsome and amusing alien. He seems to be reciprocating, though they both struggle against an untimely romantic entanglement.

Will Kati and Mikal escape from the Drowned Planet? Can they ultimately bring the slavers to justice, as Mikal has sworn to do? Can they free the remaining captives of the slavers, as Kati has promised to do? Read this book and the rest of the series to find out all.

At about 200,000 words (equivalent to a paperback of about 400 pages), the book is an excellent value.
