Step by Step Calculations Step 1 : Use formula for standard deviation, σ = √[(1/N)Σi(xi-μ)2]. Step 2 : Where σ - the standard deviation N - number of data points ; xi - the random variable where i takes values from 1 to N ; Step 3 : μ- the mean of the data set; Know More About Factor Polynomial

Then write the final answer for σ . Calculate the standard deviation for 2,3,4,5,6 ; Step 1 : Use formula for standard deviation; σ = √[(1/N)Σi(xi-μ)2] ; N= 5; Mean = μ =2+3+4+5+65 ; μ = 205 ; μ = 4; Step 2 : Next calculate ( xi - μ )2 ; xi = the random variable ,i.e. 2,3,4,5,6 ; (2-4)2 = 4; (3-4)2 = 1; (4-4)2 = 0; (5-4)2 = 1; (6-4)2 = 4; -----------= 10 ; ------------Σ ( xi - μ )2 = 10; Step 3 : Variance =Σ ( xi - μ )2/N Variance = 10/5 ; Variance = 2; Standard deviation = σ = √[(1/N)Σi(xi-μ)2] ; σ = √ [(1/5)2]; Answer : 1.414 Learn More About How to Solve Multi Step Equations

Calculate the standard deviation for 10,20,30,40; Step 1 : Use formula for standard deviation; σ = √[(1/N)Σi(xi-μ)2] ; N= 4; Mean = μ = 10+20+30+405 ; μ = 100/4 ; μ = 25; Step 2 : Next calculate ( xi - μ )2 ; xi = the random variable ,i.e. 10,20,30,40 ; (10-25)2 = 225 ; (20-25)2 = 25; (30-25)2 = 25; (40-25)2 = 225; ---------------= 500 ; ---------------Σ ( xi - μ )2 = 500; Step 3 : Variance = Σ ( xi - μ )2/N Variance = 500/4; Variance = 125 ; Standard deviation = σ = √[(1/N)Σi(xi-μ)^2] ; σ = √ [(1/4)125]; Answer : 11.180
