ISS 2016 Statistics Paper-1 Solution: Question 79 (Identifying Statistical Software Tools)
We're continuing our question-by-question walkthrough of the ISS Statistics Paper-1 archive, working through each previous year's test booklet in order so that aspirants can build familiarity one question at a time. Today's question comes from the ISS 2016 Statistics Paper-1, and it tests something a little different from the usual distribution theory or estimation problems: how well you actually know the tools of the trade.
Quick Summary
Topic:General awareness — statistical software identification
Question Reference:ISS 2016, Statistics Paper-1, Question 79
Correct Answer:Option (b) — 1, 3 and 4 only
Here is the question exactly as it appears in the test booklet:
Q79. Which of the following are statistical softwares?
Minitab
GIMP
R
SPSS
Select the correct answer using the code given below:
(a) 1, 2 and 3 only
(b) 1, 3 and 4 only
(c) 1, 2 and 4 only
(d) 2, 3 and 4 only
Step 1: Understand what the question is actually asking
This is a "match the statement to the code" style question, which is extremely common in the ISS General Studies and Statistics papers. You are given four items, numbered 1 to 4, and you must decide which of them belong to a particular category — here, "statistical software." Once you decide which items qualify, you match your selection against the four lettered options (a) through (d) to find the one that lists exactly your selected items and no others.
This means you don't actually need to know anything about statistical theory to answer this question. You need to know, factually, what each of the four named tools is actually used for. So let's go through them one at a time.
Step 2: Examine each item individually
Item 1 —Minitab. Minitab is a dedicated statistical software package, widely used for data analysis, quality control (control charts, Six Sigma work), regression, ANOVA, and hypothesis testing. It is built specifically for statistical computation. Minitab qualifies.
Item 2 —GIMP. GIMP stands for "GNU Image Manipulation Program." It is a free, open-source raster graphics editor — the kind of tool you would use to edit photographs, draw images, or do pixel-level graphic design work, comparable in purpose to Adobe Photoshop. It has absolutely nothing to do with statistical computation, data analysis, or hypothesis testing. GIMP does not qualify.
Item 3 —R. R is a programming language and free software environment built specifically for statistical computing and graphics. It is one of the most widely used tools in applied statistics, data science, and academic research, with thousands of statistical packages built on top of it. R clearly qualifies.
Item 4 —SPSS. SPSS ("Statistical Package for the Social Sciences") is a long-established commercial statistical software suite used heavily in social science research, market research, health sciences, and survey data analysis. It qualifies without question.
Pro Tip: On questions like this, the exam setters almost always hide one deliberately unrelated "decoy" item among three genuine ones, counting on the fact that unfamiliar acronyms get skipped over without a second look. The habit worth drilling until it becomes automatic — something that gets reinforced heavily in how these software-awareness questions are taught — is to mentally expand every acronym in the options before eliminating anything. The moment you expand GIMP to "GNU
Step 3: Match your selection to the given codes
From Step 2, the items that qualify as statistical software are 1 (Minitab), 3 (R), and 4 (SPSS). Item 2 (GIMP) does not qualify. So the correct selection is "1, 3 and 4 only."
Now compare this against the four options:
(a) 1, 2 and 3 only — includes GIMP (wrong), excludes SPSS (wrong). Incorrect.
(b) 1, 3 and 4 only — Minitab, R, SPSS. Matches our selection exactly.
(c) 1, 2 and 4 only — includes GIMP (wrong). Incorrect.
(d) 2, 3 and 4 only — includes GIMP (wrong), excludes Minitab (wrong). Incorrect.
Option (b) is the only one that lists exactly the three genuine statistical software tools and leaves out GIMP.
Final Answer and Verification
The correct answer is Option (b): 1, 3 and 4 only.
Checking this against the official ISS 2016 answer key (Test Booklet Series A), the key lists the answer to Question 79 as (b)as well. Our independently reasoned answer matches the official key exactly, so there is no discrepancy to flag here.
Why This Question Matters
It's tempting to dismiss software-awareness questions as "easy marks" that don't deserve preparation time, but that's exactly why they trip people up under exam pressure — candidates who are busy mentally rehearsing formulas for the numerical questions often skim past a question like this without actually reading each option carefully, and lose a mark they absolutely should not lose. As statistics has moved from purely manual computation toward software-driven analysis, the ISS exam has increasingly tested whether candidates are aware of the standard tools actually used in the field — R, SPSS, SAS, Minitab, Python's statistical libraries, and so on — rather than testing only theoretical derivations. Being able to instantly separate genuine statistical tools from unrelated software (image editors, spreadsheet programs, presentation software) is a basic but necessary piece of exam literacy.
Is GIMP used for any kind of data work at all?
No. GIMP is exclusively an image and graphics editing tool, similar to Photoshop. It has no built-in capability for statistical analysis, hypothesis testing, or numerical computation, which is precisely why it was included here as the incorrect option.
Are Minitab, R, and SPSS used for the same kind of work?
Broadly yes, though with different strengths. Minitab is popular in industrial and quality-control settings, SPSS is widely used in social science and survey research, and R is a general-purpose statistical programming language favoured in academia and data science. All three are built specifically to perform statistical computation.
Does the ISS exam expect candidates to know how to actually operate these software packages?
Paper-1 of the ISS Statistics exam tests conceptual awareness rather than hands-on software operation — you are expected to know what each tool is used for and its general nature, not to write code or operate the software during the exam itself.
What other statistical software names could appear in a similar question?
Commonly tested names include SAS, STATA, Python (with libraries such as NumPy and pandas), Excel, EViews, and Gretl. It is worth keeping a short mental list of what each one is primarily used for, since this type of question tends to recur across different years with different name combinations.
How should I prepare for this kind of general-awareness question if it isn't covered in standard statistics textbooks?
This is exactly the kind of practical, outside-the-textbook knowledge that tends to get covered through dedicated current-awareness notes in structured coaching, rather than through theory-heavy study material alone; keeping a running list of software names and their one-line purpose as you encounter them in practice papers works well.
If I genuinely don't recognise one of the names in such a question, what's the best strategy?
Try to eliminate options using the names you do recognise first. In this question, even without knowing GIMP at all, recognising that Minitab, R, and SPSS are definitely statistical tools would narrow you down to option (b) by elimination, since it's the only option containing all three.
