Answer
Explanation:
Step1: Count the number of data - points
There are 2 + 2+ 3 + 4+ 1 = 12 data - points.
Step2: Calculate the sum of the data - points
(1×2)+(2×2)+(3×3)+(4×4)+(5×1)+(6×0) = 2 + 4+9 + 16+5+0 = 36.
Step3: Calculate the mean
The mean $\bar{x}=\frac{\text{Sum of data - points}}{\text{Number of data - points}}=\frac{36}{12}=3$.
