                ### Assistant: To find the coefficient of variation (C.V.) for each group, we first need to calculate the standard deviation (σ) and the mean (x̄) for each group. The formula for C.V. is: C.V. = (σ/ x̄) × 100
For Group A, the standard deviation (σ) is 15.09 and the mean (x̄) is 44.6. So, C.V. for Group A is: C.V. = (15.09/44.6) × 100 = 33.83
For Group B, the standard deviation (σ) and the mean (x̄) need to be calculated following a similar process as for Group A.
After calculating the C.V. for both groups, we can compare them to determine which group is more variable. , The answer is To compare the variability or dispersion of two series, we calculate the coefficient of variance for each series. The series having greater C.V. is said to be more variable than the other. The series having lesser C.V. is said to be more consistent than the other.
