Step 2: Select Model

Choose "Simple random sample model"
Choose "Value Features "
Choose " Scale" in the types of sample value choice (If the samples value attribute is proportion, that is, maximum value less than 1, minimum value greater than 0, then select the proportion value)
Filled out a confidence level 0.95
