The correct answer is:
The average scores of $\mathrm{A}$ and $\mathrm{B}$ are not same but $\mathrm{B}$ is consistent $\quad$
Average score of $\mathrm{A}=\frac{71+56+45+89+54+44}{6}$ $=\frac{359}{6}=59.83$
and average score of $\mathrm{B}=\frac{55+74+83+54+38+52}{6}=\frac{356}{6}=59.33$
Variation is lesser in case of B than A. So, the average scores of A and B are not same but B is consistent.
and average score of $\mathrm{B}=\frac{55+74+83+54+38+52}{6}=\frac{356}{6}=59.33$
Variation is lesser in case of B than A. So, the average scores of A and B are not same but B is consistent.
