Before you spend anything, check what your university library already provides. Many Indian institutions license statistical software for research scholars, and a large number of scholars pay for tools they already have access to. Once that is settled, the choice comes down to what your examiners will recognise and what you will still be able to open after you graduate.
| Tool | Cost | Covers standard thesis analysis | Learning curve | Access after graduation | Best suited to |
|---|---|---|---|---|---|
| IBM SPSS Statistics | Commercial; often licensed by universities | Yes, via menus | Moderate | Ends with your licence | Scholars whose institution licenses it |
| R | Free and open source | Yes, and well beyond | Steep | Permanent | Scholars continuing in research |
| JASP | Free and open source | Yes, via menus | Low | Permanent | Scholars with no institutional licence |
| Microsoft Excel | Commercial; usually already available | Partly, with manual formulas | Low for basics | Depends on your licence | Descriptive work and data preparation |
The criteria used here
- What it actually costs you. Not list price, but what you personally must pay given your institutional access.
- Recognition. Will your guide and examiners read the output without friction?
- Coverage. Does it handle everything in your analysis plan without switching tools midway?
- Durability. Can you still open your analysis in five years, after your student status ends?
That fourth criterion is routinely ignored and matters more than scholars expect. A thesis analysis you cannot reopen because a licence expired is a genuine problem when a reviewer asks you to rerun something for a paper two years later.
1. IBM SPSS Statistics
SPSS is placed first on recognition rather than capability. Indian methodology teaching, textbooks and a very large share of completed theses use it, so when you paste SPSS output into your results chapter, your guide and examiners recognise the format instantly and attention goes to your findings rather than your tooling.
Strengths. Menu-driven access to everything a thesis normally requires: descriptives, item-total correlations, reliability coefficients, t-tests, ANOVA, correlation, regression and the associated assumption checks. No programming needed, and abundant local training material exists.
Weaknesses, stated plainly. It is commercial and expensive at personal cost. Unofficial copies carry legal and data-security risks and are not a defensible choice for research you will submit and publish. Access typically ends with your student status, so export your outputs and datasets in open formats before you graduate. And a recurring confusion for new users: SPSS has no menu item called item validity — you run a correlation and interpret it as item-total correlation.
2. R
R is free, open source, and effectively unlimited in analytical scope. For a doctoral scholar it has one decisive advantage over every menu-driven alternative: your analysis becomes a script.
Strengths. Reproducibility is the real argument. When you find a data-entry error in month eight, you correct the file and rerun the script, rather than repeating fifty menu selections and hoping you remember every setting. That same script is what lets you rerun an analysis for a reviewer years later. Coverage extends well past standard tests into specialised methods your field may require, and it costs nothing permanently.
Weaknesses. The learning curve is the steepest here by a wide margin. If your submission is weeks away and you have never written code, beginning R now adds risk rather than removing it. The honest recommendation is to start learning it early in your candidature, when the investment has years to repay, and not under deadline pressure.
3. JASP
JASP is an open-source project supported by the University of Amsterdam and free to download and use. Its interface deliberately resembles conventional statistical software, so anyone who has seen SPSS adapts quickly.
Strengths. Free and fully legal, which removes the licensing question entirely for scholars without institutional access. Results update live as you change options, which is unusually good for catching mistakes and for actually learning what each setting does. Output tables follow APA conventions already, so they need less reformatting than SPSS output. Both classical and Bayesian versions of standard analyses are available.
Weaknesses. Familiarity among Indian guides and examiners is lower. If your guide specifically expects SPSS output, using JASP creates a conversation you do not need weeks before submission. For highly specialised analyses its coverage is narrower than SPSS or R.
4. Microsoft Excel
Excel is where most scholars clean and organise data, and that is its real strength. It can also compute validity and reliability manually: correlate each item against the construct total, then compute item variances, total variance and apply the reliability formula.
Strengths. Already installed and familiar. Because you build every step yourself, you genuinely understand where each number comes from, which is real preparation for viva questions about your analysis.
Weaknesses. Error risk rises sharply with the number of items, and formula errors are hard to detect because the output still looks like a plausible number. Excel also lacks most of the inferential procedures a doctoral analysis plan requires, so you will switch tools partway regardless. Use it for preparation and description, not as your analysis platform.
Recommendation by situation
- Your institution licenses SPSS: use it. The most widely recognised option is already free to you.
- No institutional licence: use JASP. Free, legal, permanent, and output needs less reformatting.
- You are in year one and intend to stay in research: learn R now, while there is time for the investment to pay off.
- Your guide expects SPSS output: follow that. Debating software is a poor use of the weeks before submission.
- You are preparing and cleaning data: Excel, then move to a statistical package for analysis.
Before you graduate, export everything
Whichever tool you use, do this before your student status ends: save your dataset in CSV, which every package reads; save your output in PDF; and if you used a script, keep it with the data. This costs an hour and protects you against losing access to your own analysis when a licence lapses.
Where Tesify sits, and where it does not
To keep this comparison honest, the boundary needs stating: Tesify is not a statistics package. It does not compute reliability coefficients, run regressions, or analyse your dataset. Use one of the four tools above for that, and remain responsible for every number you report.
What Tesify handles is the writing around the analysis: describing your procedure in the methodology chapter, narrating results, and keeping what you said you would do consistent with what you report doing. That consistency is where chapters are most often returned even when the statistics are correct.

Decide the analysis before the tool
Tool choice matters far less than analysis choice. Running the wrong test correctly in expensive software is still the wrong test, and examiners probe the reasoning rather than the software.
If you are still designing the study, settle feasibility and data access first using where to find data for your Indian thesis and how to choose a PhD research topic in India by discipline. When you reach publication, the current position on journal verification is set out in how to verify a journal in India in 2026.
Frequently asked questions
Will SPSS and R give different results?
For the same test on the same data, no. The formulas are identical. Small differences in decimal places arise from rounding or default settings. A large discrepancy nearly always means the data or the specification differs, not the software.
Is JASP accepted by Indian universities?
Universities assess your analysis, not your software brand, and JASP output is legitimate. The practical question is whether your guide is comfortable reading it, which is worth asking before you commit.
Should I name the software in my thesis?
Yes, with the version number. Naming the tool and version is standard practice and lets a reader understand exactly how your results were produced.
Can I switch tools partway through?
Yes, if you export your data as CSV, which all four read. Redo any completed analysis in the new tool so everything you report comes from one consistent source.
Which tool is best for structural equation modelling?
SEM needs dedicated tools rather than general packages. Several exist, some commercial and some free, and R has well-supported packages for it. Confirm what your department uses and can support before committing, because local support matters more than features.
Is it worth paying someone to do my analysis?
Think hard about this. The risk is not the numbers but the viva: examiners routinely ask why a test was chosen and what the output means. If you cannot answer, correct results will not help you. Whatever assistance you use, understand every step well enough to defend it.
How long does it take to learn enough SPSS?
Most scholars reach working competence for standard descriptive and inferential tests within a few focused sessions, especially with departmental or library training. The analysis is usually faster than the writing that follows.
Does Excel have a statistics add-in?
It includes an analysis toolpak that must be enabled and offers several basic procedures. It remains limited for assumption checking and post-hoc tests, so treat it as suitable for descriptive work rather than a full analysis plan.
Do I need to include output screenshots in my thesis?
Most Indian universities expect analysis output as an appendix, with cleanly retyped tables in the main text. Check your department’s format requirements, since some specify whether screenshots are acceptable.
What if my institution’s licence expires mid-candidature?
Export your dataset and outputs immediately in open formats, then move to a free tool and rerun your analysis to confirm the results match. Discovering the lapse when you need to revise for examiners is far worse than planning for it.
