V experimentech vědci používají postupný proces vývoje výzkumné otázky a poté na tuto otázku odpovídají provedením testů. Hlavním cílem je stanovit kauzální vztah mezi jedním faktorem, který se mění, nezávislou proměnnou, a faktorem, který je ovlivněn, závisle proměnnou. Dobře navržený experiment má proměnné, které jsou pečlivě kontrolovány, což minimalizuje vliv cizích proměnných.

In experiments, scientists use a stepwise process of developing a research question, then answering that question by performing tests. The main goal is to establish a causal relationship between one factor that is being changed, the independent variable, and the factor that is influenced, the dependent variable. A well-designed experiment has variables that are carefully controlled, which minimizes the influence of extraneous variables.

These are the current scores badges for this post were claimed with.

For example, if a badge has a score of 50, then you can claim it for yourself if your recording receives 51 points or more.

En els experiments, els científics utilitzen un procés gradual per desenvolupar una pregunta d'investigació i després responen a aquesta pregunta mitjançant la realització de proves. L'objectiu principal és establir una relació causal entre un factor que s'està canviant, la variable independent, i el factor que està influenciat, la variable dependent. Un experiment ben dissenyat té variables que es controlen acuradament, la qual cosa minimitza la influència de variables alienes.

В експериментите учените използват поетапен процес на разработване на изследователски въпрос, след което отговарят на този въпрос чрез извършване на тестове. Основната цел е да се установи причинно-следствена връзка между един фактор, който се променя, независимата променлива, и факторът, който е повлиян, зависимата променлива. Добре проектираният експеримент има променливи, които се контролират внимателно, което минимизира влиянието на външни променливи.

পরীক্ষা-নিরীক্ষায়, বিজ্ঞানীরা একটি গবেষণা প্রশ্ন তৈরি করার ধাপে ধাপে প্রক্রিয়া ব্যবহার করেন, তারপর পরীক্ষা করে সেই প্রশ্নের উত্তর দেন। প্রধান লক্ষ্য হল একটি কারণের মধ্যে একটি কার্যকারণ সম্পর্ক স্থাপন করা যা পরিবর্তিত হচ্ছে, স্বাধীন পরিবর্তনশীল, এবং যে ফ্যাক্টরটি প্রভাবিত হয়, নির্ভরশীল পরিবর্তনশীল। একটি ভাল-পরিকল্পিত পরীক্ষায় ভেরিয়েবল রয়েছে যা সাবধানে নিয়ন্ত্রিত হয়, যা বহিরাগত ভেরিয়েবলের প্রভাবকে কমিয়ে দেয়।

في التجارب ، يستخدم العلماء عملية تدريجية لتطوير سؤال بحث ، ثم الإجابة على هذا السؤال عن طريق إجراء الاختبارات. الهدف الرئيسي هو إنشاء علاقة سببية بين عامل واحد يتم تغييره ، والمتغير المستقل ، والعامل المتأثر ، المتغير التابع. تحتوي التجربة المصممة جيدًا على متغيرات يتم التحكم فيها بعناية ، مما يقلل من تأثير المتغيرات الخارجية.
