In advanced tab , ​We have number of samples – This this examples it is 1000​

1. Confidence interval​

2. Stat type​

3. Track raw samples ​

4. Return type

Return type with example
==============================

1. Return type – Single bootstrap sample

a. This return type returns 25 rows dataset.​

b. It will return the same number of input rows in the output

2. Return type – Raw bootstrap sample​

a. This will return  25 *(number of bootstrap samples provided in the input) number of rows  dataset for selected columns.​

b. In this case it will return 25000 rows

3. Return type –  Sample statistics​

a. This will return (number of bootstrap samples provided in the input) number of rows dataset​

b. In this case it will return 1000 rows as number of samples are 1000
