# What is the difference between runif () and rnorm () functions in R

**RUNIF ()**

runif function generates a list of random numbers between an interval. For example,

```
# Generates 100 random numbers between 0 and 100
> runif(100, min = 0, max = 100)
```

**RNORM ()**

rnorm function generates a set of random numbers with a defined mean and standard deviation. For example,

```
# Generates 100 random numbers with a mean of 100 and standard deviation of 10
> rnorm(100,mean=100,sd=10)
```
