வடிவியல் சராசரி n எண்களின் பெருக்கத்தின் n வது மூலமாக வரையறுக்கப்படுகிறது.
தரவுத்தொகுப்பு \(\rm {\textstyle \left\{a_{1},a_{2},\,\ldots ,\,a_{n}\right\}}\) இன் வடிவியல் சராசரி:
\(\rm GM = \rm {\textstyle \left\{a_{1}\times a_{2}\times\,\ldots \times\,a_{n}\right\}}^{\frac{1}{n}}\)
கணக்கீடு:
கண்டுபிடிக்க வேண்டியவை: 6, 8, 16 மற்றும் 27 இன் வடிவியல் சராசரி
இங்கே n = 4
இப்போது,
\(\rm GM = \rm ({{6 \times 8 \times 16 \times 27}})^{\frac{1}{4}}\)
\(= \rm ({{2 \times 3 \times 2^3 \times 2^4 \times 3^3}})^{\frac{1}{4}} \\ =(2^8 \times 3^4)^{\frac{1}{4}}\\ = (2^2 \times 3)\\=12\)
