Explanation:

Step1: Count data - point frequencies

There is 1 data - point at 0, 1 at 1, 2 at 2, and 1 at 3.

Step2: Calculate the sum of data - points

The sum is \(0\times1 + 1\times1+2\times2 + 3\times1=0 + 1+4 + 3=8\).

Step3: Calculate the total number of data - points

The total number of data - points is \(1 + 1+2 + 1=5\).

Step4: Calculate the mean

The mean \(\bar{x}=\frac{8}{5}=1.6\).

Answer:

1.6
