Analysis about can the Goverment take a decision or not?
Mean: 1. Agree: (43.2+12)/2 = 27.6
2. Strongly Agree: (27.9+10)/2 = 18.95
3.Disagree: (5.6+3.1)/2 = 4.35
4. Strongly Disagree: (0+0)/2 =0
On an averege About 27.6 people agree that Goverment can take decision and on an averege about 18.95 people strongly agree and 4.35 people are disagree about it.

N: Total number of observations: 4
Arrenging the observations by asending order median is Size of (N+1)/2 observation:
Median = Size of (4+1)/2 = 2.5
= Size of second obs+ 0.5 ( Size of third obs- Size of second observation
= 2+0.5(3-2) = 2.5
Median= (18.95+4.35)/2 = 23.3
Mode: Mode is the maximum number of times an event occur: 43.2 males are agree about decision; So mode is 43.2
