Unsupervised Learning - Kmeans Week 11 Challenge

1.Why there is a difference in the formula of variance for population and sample?-> Population variance Sample variance 1.σ2=∑(xi−μ)2/N 1. s2=∑(xi−¯x)2./(n-1)where N is the size of the population The xi tends to be closer toconsisting of x1,x2,…xN and μμ is the their average…

The features included in this dataset are: Age (in years) Sex (male or female) Body Mass Index (BMI) Number of children…

1)Calculate all 4 business moments using pen and paper for the below data set 1) mean µ= ∑(x1) * p(x) = 0*0.35+1*0.25+ 2*0.15 + 3*0.15 + 4*0.10 = 0 + 0.25 + 0.3 +0.45 +0.4 = 1.4 2) Second business movement Variance σ2 = ∑(x1-µx)^2 *P(x) σ2 = (0-1.4)^2 *0.35 + (1-1.4)^2 *0.25 + (2-1.4)^2…
