# mean (média)
mean = sum(x)/len(x)

# Deviation from the mean (desvio da média)
desv = [number - mean for number in x]

# Average deviation from the mean (desvio médio)
avg_desv = sum(desv)/len(x)

# Sum of squares (soma dos quadrados)
ss = sum([math.pow((number - mean), 2) for number in x])

# Variance (variância)
var = ss/len(x)

# Standard deviation (desvio padrão)
sigma = math.sqrt(var)
