Average = (0+0+1+2+3)/5 = 1.2
Variance = 1/N * SUM (x-E(x))2 = 1/5 * 6.8 = 1.36
Answer: Variance = 1.36
Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.
The standard normal distribution or the Gaussian distribution with mean 0 and variance 1.
0!=1 =(0! + 0! + 0! + 0! + 0!)! =(1 + 1 + 1 + 1 + 1)! =(5)! =120.
A normal distribution can have any value for its mean and any positive value for its variance. A standard normal distribution has mean 0 and variance 1.
The variance is: 58.0
The variance is: 0.666666666667
0.666666666667
Variance = sigma((value - mean)2) / (# values - 1) Mean = (0+1+1+2)/4 = 1 Variance = ((0-1)2+(1-1)2+(1-1)2+(2-1)2)/(4-1) Variance = (1+0+0+1)/3 Variance = 2/3 Variance ~ 0.667
z-scores are distributed according to the standard normal distribution. That is, with the parameters: mean 0 and variance 1.
Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.
Variance
Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.

It is a normal curve with mean = 0 and variance = 1.
Program in CHere is a program in C to calculate mean variance and standard deviation: #include#includevoid main(){float a[50],sum=0,vsum=0,mean,variance,sd;int n,i;printf("Enter the no of valus");scanf("%d",&n);printf("Enter the no of valus");for(i=0;i
