How can we help?
Which files can I upload?
CSV, Excel (.xlsx/.xls), SPSS (.sav, with value labels) and Stata (.dta), up to 25 MB. Use one header row with one name per column.
Why does it say my file can't be read?
Usually merged header cells, several tables on one sheet, or a title row above the headers. Keep one header row and one table per sheet, then upload again.
Is there data I can practise with?
Yes: a survey, monthly sales, patient survival and meta-analysis studies, all simulated. Download them from the Sections page.
Which test should I use?
Use the test selector on the Sections page, or Ask your data in plain English. Every result also shows its parametric or non-parametric twin and the assumption checks that decide between them.
My results differ from SPSS. Why?
Check missing values (we use all available cases per test), whether a continuity correction was used, and Type III sums of squares for factorial ANOVA. Document 1 shows every setting, and Pro gives you the SPSS syntax to compare directly.
Can I use Kmex Studio for my dissertation?
Yes, for analysis, learning and drafting. Check your university's rules on AI use and write the final text in your own words.
How do I write an SEM model?
One line per factor or path. Factors: Quality =~ q1 + q2 + q3. Paths: Loyalty ~ Quality. Each factor needs at least 3 items and about 100+ responses.

Cancel in Billing at any time; you keep Pro until the end of the period. Pro is refundable within 7 days of your first payment: send us a message.
Do you have a plan for departments?
Yes: the Team plan, $5 per seat per month billed yearly, minimum 5 seats, with automatic joining by school email domain. Create one from the Team page.
How do expert jobs work?
Describe the job and your budget, get a quote, pay a 50% deposit, approve a preview, then pay the balance to download everything.
What if I'm not happy with the expert's work?
Ask for a revision in the chat first. If it isn't resolved, open a dispute from the request page within 7 days of delivery. We resolve disputes within 5 working days.
Is my data safe?
Your data is stored privately, deleted after 30 days unless you save the project, and never used to train AI models. AI features see computed results or column names, never your raw rows.
How do I delete my account?
