 1. 85,96,76,108,85,80,100,85,70,95
2. 3,13,11,11,5,4,2
3. 3,23,13,11,15,3,5,4,2
4. 69,66,67,69,64,63,65,68,72
5. 4,14,12,16,6,3,1,2,3
6. 73,70,71,73,68,67,69,72,76,71
7. 10,50,30,20,10,20,70,30

Example1. Calculate Geometric mean from the following data
`3,13,11,15,5,4,2`Solution:Geometric mean :| `x` | `log(x)` | | 3 | 0.4771 | | 13 | 1.1139 | | 11 | 1.0414 | | 15 | 1.1761 | | 5 | 0.699 | | 4 | 0.6021 | | 2 | 0.301 | | --- | --- | | `sum log(x)=5.4106` |
GM of X `= Antilog((sum flog(x))/n)` `= Antilog((5.4106)/(7))` `= Antilog(0.7729)` `= 5.9285`
