Over deze dienst
Als een expert statisticus zet ik rommelige datasets om in publicatieklare resultaten. Ik overbrug de kloof tussen ruwe data en geaccepteerde manuscripten voor onderzoekers en PhD-studenten.
Waarom ik?
- Publicatiegericht: Ik weet wat peer reviewers eisen.
- Duidelijkheid: Ik leg de "waarom" achter de cijfers uit.
- Veiligheid: 100% vertrouwelijk.
Software beheersing & technieken:
- SPSS: Beschrijvende statistieken, ANOVA, regressie, t-toetsen, betrouwbaarheidstests en meer.
- R Studio: Geavanceerde codering, data cleaning, aangepaste visualisaties (ggplot2).
- SmartPLS / AMOS: SEM (structurele vergelijking modellering), CFA, padanalyse.
- RevMan: Meta-analyse, forest plots, biasrisicobeoordeling.
Mijn werkwijze:
- Data cleaning: Omgaan met outliers & ontbrekende waarden.
- Assumptietesten: Normaliteit & homoscedasticiteit controleren.
- Hypothese testen: Strenge analyse volgens jouw doelen.
- Visualisatie: Publicatieklare grafieken/diagrammen.
- APA rapportage: Interpretatie in duidelijk Engels (Results sectie).
Ben je klaar om geaccepteerd te worden?
NEEM ALSTUBLIEFT contact met mij op VOORDAT je bestelt.
En laten we je dataset en doelen bespreken om de perfecte analyse te garanderen.

Working with Omar was easy; he was professional and friendly while staying on schedule. Even when I had so many questions, he went above and beyond by providing an additional document I requested. Yes, it was a simple request, but it matters that he did not hesitate to say yes. I will work with him again, great job, Mr. Ghamen!!
