0 Next we discuss an important concept of setting seed 1

So when we are running random functions it will be always giving us random values 2

That random value is being generated through a function 3

If you give it an input through a seed it will give a particular value to you 4

So seed 5

Comes to use many times 6

For example if you have set of random values and you want to get the same set of random values again you'll set a 7

seed before getting random values 8

If I am teaching and I am showing you an example 9

And my example has some random values and If I want you to have the same random values 10

I will set the sead 11

And I'll let you know what is the value of that seed so that you can set the same seed 12

We both will get the same random values 13

This is what we will do in the example also we will set seed 14

And both of us will get the same values 15

Seed value can be between -1 to 1 16

And both of them can be included 17

and it can have any decimal value also 18

So, this is how we set a seed 19

We will write select set seed of 20

Point 5 21

Once you have set the seed 22

When you run the random function it will give you a particular value 23

Every time you run 24

The random function after setting seed at .5 it will give you the same random value 25

The second time you run the random function, it will give you new value 26

But this value will 27

Always remain same what this means is, whenever you set the seed to 0.5 the first random 28

Function will give you same value, the second random function will give you a different value 29

than the 1st random function but it will be always same 30

If you do not understand this, let us look at an example you will get what I am trying to say 31

So let us first select setseed to 0.5 32

Setseed has Run successfully 33

Now let us 34

run the random function. select random 35

So this gives a random value of .5500 36

25. Let us write this is as a comment so that we remember it 37

Now run the random function again 38

So it is now given a value of 39

0.29531 40

Now let us set 41

Seed again 42

Write select set seed 0.5 43

Now the seed is again back to .5 44

Now when we run the random function 45

we'll get 46

The same value 47

I hope if you are doing it with me you are getting the same values as I am 48

let us run the random function again 49

This will be same as 50

.295311 51

So this is what setting seed helps you do. It helps to get 52

the same set of random values 53

So that you can repeat the calculations
