Dear all,

I have 10 sample results. Normally my sample set include 100 sample but before analysing the remaining 90 samples, I want to simulate big data by using 10 sample result. I apply this approach by using SSPS monte carlo simulation but ı do not know how can i create 100 random sample result by using 10 sample result. Is there anyone help me for this.

Solution

It is simple to do. I am using the *Big Class* data set from the sample data library.

- Select
**Rows**>**Add Rows**. Add 90 rows in your case. I added 60 to the existing 40 in*Big Class*. - Select
**Cols**>**New Column**. I called it*Simulated weight*for*Big Class*example. - Add a formula that samples without replacement from the existing variable, weight in this case.

Making this formula is easy:

- Select the source data column.
- Select
**Row**>**Subscript**. - Select
**Random**>**Random Integer**. - Enter
**1**for the lower limit. - Click
**Insert**("^") key. - Enter
**10**, in your case, 40, in my case for the upper bound.

Learn it once, use it forever!
