பிளாலாக் (1960) பெரும்பாலான மாதிரி முறைகளை இரண்டு வகைகளாக வகைப்படுத்தலாம் என்று குறிப்பிட்டார்: நிகழ்தகவு அல்லாத மாதிரி முறைகள் மற்றும் நிகழ்தகவு மாதிரி முறைகள்.

நிகழ்தகவு அல்லாத மாதிரி முறைகள் நிகழ்தகவு முறைகள்
  • இந்த மாதிரியில் சேர்க்கப்படும் மக்கள்தொகையின் உறுப்பு அல்லது தனிமங்களின் குழுவின் நிகழ்தகவை மதிப்பிடுவதற்கு எந்த வழியும் இல்லை.
  • நிகழ்தகவு அல்லாத மாதிரி முறைகள் என்பது மாதிரியின் குணாதிசயங்கள், மாதிரி பெறப்பட்ட மக்கள்தொகையின் அளவுருக்களை எவ்வளவு நெருக்கமாக மதிப்பிடுவதற்கு எந்த அடிப்படையையும் வழங்கவில்லை. ஏனென்றால், நிகழ்தகவு அல்லாத மாதிரிகள் சீரற்ற மாதிரியின் நுட்பங்களைப் பயன்படுத்துவதில்லை.
  • நிகழ்தகவு அல்லாத மாதிரி முறைகளின் முக்கியமான நுட்பங்கள் இடையூறு, தற்செயலான அல்லது வசதியான மாதிரி, ஒதுக்கீட்டு மாதிரி, நோக்க மாதிரி, பனிப்பந்து மாதிரி​. 
  • நிகழ்தகவு மாதிரி முறைகள் என்பது மாதிரியில் ஒவ்வொரு உறுப்பு அல்லது தனிநபரையும் சேர்ப்பதற்கான நிகழ்தகவு அல்லது நிகழ்தகவை தெளிவாகக் குறிப்பிடுகின்றன.
  • மாதிரி அலகுகளைத் தேர்ந்தெடுப்பதில் இவை சார்பு இல்லாதவை.
  • அவை மாதிரி பிழைகளை மதிப்பிடுவதற்கும், அவற்றின் துல்லியம், துல்லியம் மற்றும் செயல்திறன் ஆகியவற்றின் அடிப்படையில் மாதிரி முடிவுகளை மதிப்பிடுவதற்கும் உதவுகின்றன, எனவே, அத்தகைய மாதிரிகளிலிருந்து பெறப்பட்ட முடிவுகள் பொதுவாக்கல் தகுந்தவை மற்றும் அவை சேர்ந்த ஒத்த மக்கள்தொகையுடன் ஒப்பிடத்தக்கவை.
  • முக்கிய நிகழ்தகவு மாதிரி முறைகள் எளிய சீரற்ற மாதிரி, அடுக்கு சீரற்ற மாதிரி மற்றும் தொகுப்பு மாதிரி மற்றும் முறையான மாதிரி.

எனவே, பனிப்பந்து மாதிரி நுட்பம் ஒரு நிகழ்தகவு ல்லாத மாதிரி நுட்பமாகும்.
