REST helps researchers, graduate students, and academics choose the correct statistical test for their study — without needing advanced statistics knowledge. Instead of searching through textbooks or guessing which test to use, REST conducts a smart, adaptive interview about your research design. It asks only the questions relevant to your specific study, then recommends the right statistical test with a clear scientific explanation. KEY FEATURES - Statistical Test Guide — An interactive interview that adapts to your answers, covering over 30 statistical tests from t-tests and ANOVA to survival analysis and logistic regression - Sample Size Guide — Calculate the ideal sample size for your study design - Questionnaire Guide — Design valid, reliable research questionnaires - Statistical Write-up Generator — Generate a ready-to-use methodology paragraph for your thesis or paper - Learning Library — Clear explanations of when and how to use each statistical test WHO IS REST FOR Undergraduate and graduate students, academic researchers, physicians, health researchers, and anyone working in social sciences, humanities, or business research who needs to choose the right statistical test with confidence. REST doesn't just name a test — it explains why, what assumptions are required, and offers valid alternatives when assumptions aren't met. Available in Arabic and English. يساعد REST الباحثين وطلبة الدراسات العليا وأعضاء هيئة التدريس على اختيار الاختبار الإحصائي الصحيح لدراستهم، دون الحاجة لخبرة متقدمة في الإحصاء. بدلاً من البحث في الكتب أو التخمين، يجري REST مقابلة بحثية ذكية ومتكيفة حول تصميم دراستك، يسأل فقط الأسئلة الضرورية، ثم يوصي بالاختبار الإحصائي الأنسب مع تفسير علمي واضح. الميزات الرئيسية: المرشد الإحصائي — مقابلة تفاعلية تغطي أكثر من 30 اختبارًا إحصائيًا مرشد حجم العينة — احسب حجم العينة المثالي لدراستك مرشد الاستبيان — صمّم استبيانات بحثية صحيحة وموثوقة كتابة التوصية الإحصائية — فقرة منهجية جاهزة لرسالتك أو بحثك المكتبة التعليمية — شروحات واضحة لكل اختبار إحصائي لا يكتفي REST بذكر اسم الاختبار فقط — بل يشرح لماذا هذا الاختبار تحديدًا، وما الافتراضات المطلوبة لصحته، ويقترح بدائل موثوقة عندما لا تتحقق هذه الافتراضات.
