Mean: The mean of a uniform distribution is the average of the outcomes. For this spinner, the mean is (1+2+3+4+5+6+7+8)/8 = 4.5.Variance: The variance is calculated using the formula for a uniform distribution: (n^2 - 1)/12, where n is the number of outcomes. Here, n = 8, so variance = (8^2 - 1)/12 = 63/12 = 5.25.Standard deviation: The standard deviation is the square root of the variance. So, standard deviation = √5.25 ≈ 2.29.
