భావన:

రేఖాగణిత సగటు: సంఖ్యల సమితి యొక్క విలువల గుణకారాన్ని ఉపయోగించడం ద్వారా కేంద్ర ధోరణిని సూచించే విలువ.

ఫార్ములా: GM = (సమితిలోని అన్ని సంఖ్యల గుణకారం) 1 / n

ఇక్కడ, సమితిలో n = మొత్తం సంఖ్యలు

ఉదాహరణ: 2, 3, 4, 5

GM = (2 × 3 × 4 × 5) 1/4 = (120) 1/4

లెక్కింపు:

G = G 1 × G 2 × G 3 ……………… .. × G r
