    Step-by-step explanation:

    First calculate the mean. This is done by adding the numbers and dividing by the count:

    sum = 6+0+4+3+2 = 15

    count = 5

    mean = 15/5 = 3

    Now create a table with the "squared deviation to the mean":

    6: (6 - 3) ² = 9

    0: (0 - 3) ² = 9

    4: (4 - 3) ² = 1

    3: (3 - 3) ² = 0

    2: (2 - 3) ² = 1

    And sum these:

    9+9+1+0+1 = 20

    Divide by the count to find σ²:

    σ² = 20/5 = 4

    Hence σ = √4 = 2
