Q. In the data set below, what is the variance?4,8,6,1,4,1,4If the answer is a decimal, round it to the nearest tenth.variance (σ2): _____
Calculate Squared Differences: Now, let's calculate the squared differences from the mean.(4−4)2+(8−4)2+(6−4)2+(1−4)2+(4−4)2+(1−4)2+(4−4)2= 0+16+4+9+0+9+0= 38
Find Variance: Finally, we divide the sum of squared differences by the number of values to find the variance.Variance σ2 = 738Variance σ2≈5.4 when rounded to the nearest tenth.
