**How do you convert a distribution to a normal distribution?**

The standard normal distribution (z distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation.

**How do you normal distribution in Matlab?**

Plot Standard Normal Distribution cdf

- Copy Command. Create a standard normal distribution object.
- pd = NormalDistribution Normal distribution mu = 0 sigma = 1. Specify the x values and compute the cdf.
- x = -3:. 1:3; p = cdf(pd,x); Plot the cdf of the standard normal distribution.
- plot(x,p)

### Can a uniform distribution be normal?

The probability is not uniform with normal data, whereas it is constant with a uniform distribution. Therefore, a uniform distribution is not normal.

**What is uniform distribution and standard normal distribution?**

Normal Distribution is a probability distribution where probability of x is highest at centre and lowest in the ends whereas in Uniform Distribution probability of x is constant. Normal Distribution is a probability distribution which peaks out in the middle and gradually decreases towards both ends of axis.

**What is difference between normal distribution and STD normal distribution and uniform distribution?**

The normal distribution is bell-shaped, which means value near the center of the distribution are more likely to occur as opposed to values on the tails of the distribution. The uniform distribution is rectangular-shaped, which means every value in the distribution is equally likely to occur.

#### How do you make an exponential distribution from a uniform distribution?

Exponential Distribution

- Compute the cdf of the desired random variable . For the exponential distribution, the cdf is .
- Set R = F(X) on the range of .
- Solve the equation F(X) = R for in terms of .
- Generate (as needed) uniform random numbers and compute the desired random variates by.

**How do you find the mean and standard deviation of a uniform distribution?**

The mean of X is μ=a+b2. The standard deviation of X is σ=√(b−a)212. The probability density function of X is f(x)=1b−a for a≤x≤b.

**Is uniform distribution discrete or continuous?**

The uniform distribution (discrete) is one of the simplest probability distributions in statistics. It is a discrete distribution, this means that it takes a finite set of possible, e.g. 1, 2, 3, 4, 5 and 6.

## How do you find Z in normal distribution?

z = (x – μ) / σ Assuming a normal distribution, your z score would be: z = (x – μ) / σ
