آشنایی با موضوع

تحلیل واریانس (Analysis of variance) که به طور اختصار ANOVA نامیده میشود یکی از تحلیل‌های پرکاربرد است که در تمامی علوم کاربرد دارد. به زبان ساده می‌توان چنین گفت که اگر شما دو یا بیش از دو گروه داشته باشید و بخواهید نمره یک متغیر را در این گروه‌ها مقایسه کنید باید از این آزمون استفاده کنید. به عبارت دیگر رابطه بین یک متغیر وابسته و یک یا چند متغیر مستقل را مورد بررسی قرار می دهد. متغیرهای مستقل کیفی هستند و متغیرهای وابسته کمی هستند. در تجزیه و تحلیل مقایسات بین آزمایشگاهی و مطالعات درون آزمایشگاهی هنگامی‌ که می‌خواهیم نتایج بیش از سه گروه مختلف (سه آزمایشگاه متفاوت و یا سه تکنسین متفاوت در یک آزمایشگاه) را به یکدیگر مقایسه کنیم، از روش آنالیز واریانس (ANOVA) استفاده می‌شود. روش ANOVA از F-test برای آزمون آماری برابری میانگین‌ها استفاده می‌کند. تحلیل واریانس از تکنیک های آماری موثر و پرکاربرد در تحقیقات اقتصادی، اجتماعی، علوم تربیتی، روانشناسی، مدیریت و حتی کشاورزی، بیولوژی و غیره است. تحلیل واریانس روشی است که بر اساس آن کل تغییرات یا پراکندگی موجود در مجموعه ای از داده ها به مولفه های گوناگون تقسیم می شوند. برای هر یک از این مولفه ها منبعی از پراکندگی وجود دارد. در این روش واریانس کل یا تغییرات کل به دو منبع یا دو مولفه واریانس بین گروه ها که نشان دهنده تفاوت های بین گروه ها است و منبع یا مولفه واریانس درون گروه ها که واریانس خطا نیز نامیده می شود و فرض می شود که ناشی از عوامل شانس یا تصادفی است، تقسیم می شود. به عنوان مثال اگر تاثیر سه روش تدریس A، B و C بر پیشرفت تحصیلی دانش آموزان در درس ریاضی مورد بررسی قرار گیرد، پس از اجرای این سه روش تدریس متفاوت، در سه نمونه از دانش آموزان سه میانگین پیشرفت تحصیلی در سه نمونه ( برای مثال سه میانگین ۱۷، ۱۶ و ۱۶/۵ ) به دست می آید. حال سوال پژوهشگر آن است که تفاوت بین این سه میانگین چگونه تفاوتی است؟ آیا ناشی از پراکندگی و تغییر بین خود افراد در درون گروه هاست و یا نه این تفاوت به عوامل فردی، خطا و شانس مربوط نمی شود بلکه مربوط به تفاوت بین گروه ها است که می تواند بیانگر تاثیر نوع روش های تدریس متفاوت در این سه گروه باشد.
