Mean= Sum of all observations divided by no of observations = 28.8 divided by 12= 2.4
To find out median we have to arrange the given raw data in organised data .
Organised data= 2.2,2.2,2.2,2.2,2.3,2.3,2.4,2.5,2.5,2.6,2.7,2.7
Median = sum of two middle most observations divided by 2
= 2.3+2.4/2
= 4.7/2
= 2.35
Here 2.2 occurs most frequently (4 times)
Mode= 2.2
