# Program in Go language to Calculate Standard Deviation using Math package

Simple program using Pow and Sqrt functions of Math package to calculate Standard Deviation of 10 numbers

### Example

```
``````
// Golang Program to Calculate Standard Deviation
package main
import (
"fmt"
"math"
)
func main(){
var num[10] float64
var sum,mean,sd float64
fmt.Println("****** Enter 10 elements *******")
for i := 1; i <= 10; i++ {
fmt.Printf("Enter %d element : ",i)
fmt.Scan(&num[i-1])
sum += num[i-1]
}
mean = sum/10;
for j := 0; j < 10; j++ {
// The use of Pow math function func Pow(x, y float64) float64
sd += math.Pow(num[j] - mean, 2)
}
// The use of Sqrt math function func Sqrt(x float64) float64
sd = math.Sqrt(sd/10)
fmt.Println("The Standard Deviation is : ",sd)
}
```

### Output

```
``````
****** Enter 10 elements *******
Enter 1 element : 3
Enter 2 element : 5
Enter 3 element : 9
Enter 4 element : 1
Enter 5 element : 8
Enter 6 element : 6
Enter 7 element : 58
Enter 8 element : 9
Enter 9 element : 4
Enter 10 element : 10
The Standard Deviation is : 15.8117045254457
