Answer:
Step-by-step explanation:
Median: First write in ascending order. If number of data's is odd, median is the middle data.
If number of data's is even, then median = average of n/2th and (n+2)/2th term.
1) 1 , 3 , 5 , 5 , 6
Median = 5
2) 3,4,10,2,1
Ascending order: 1,2,3,4,10
Median = 3
3) 4, 5,7,11
Median = (5+7)/2 = 12/2 = 6
4) 1,1,2,6
Median = (1+2)/2 = 3/2 = 1.5
5) 2,2,3,3,,5,7
Median = 3+3/2 = 6/2 = 3
6)1,2,4,6,7,7
Median = (4+6)/2 = 10/2 = 5
7) 2,2,3,6,7,8
Median = (3+6)/2 = 9/2 = 4.5
8)1,2,3,14,17,18
Median = (3+14)/2 = 17/2 = 8.5
Mean= Sum of all the items÷ number of items
1)Mean = (1+2+3+2)÷4 = 8÷2 = 4
2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3
3)Mean = (5+4+6+1)÷4 = 16÷4 = 4
4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4
5)Mean =(10+11+9+12+8)÷5=50÷5 = 10
6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4
7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1
8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5
