Find the mean steps
જવાબ : Mean = 29.17
જવાબ : The mode is 30.
જવાબ : the mode is = 5
જવાબ : 65
જવાબ : 61
જવાબ : In S_{1} : Number 9 occurs 3 times
∴ Mode of S_{1} Series = 9
In S_{2} : Number 7 occurs 3 times
∴ Mode of S, Series = 7
After combination:
In S_{1} & S_{2} : No. 8 occurs 4 times
∴ Mode of S_{1} & S_{2} taken combined = 8
So, mode of S_{1} & S_{2} combined is different from that of S_{1} & S_{2} taken separately.
જવાબ : Mode = 3(Median) – 2(Mean)
35.3 = 3(X) – 2(30.5)
35.3 = 3(X) – 61
96.3 = 3 X
