Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a package called Dinosaur sampling.  You'll need to create 3 variables:

Variable What it will hold
DinoCount1 The number of dinosaurs going down the left-hand pipe.
DinoCount2 The number going down the right-hand pipe.
DinoTotal The number coming out the bottom.

All of this will make sense when you look at the data flow diagram below:

Percentage sampling flow diagram

We'll use a Percentage Sampling transformation to split the data into two streams, wtih 50% of the dinosaurs in each.

The control flow should end with a script to display the results found:

The data flow and script tasks

The Show results script should have 3 ReadOnly variables defined for it.

 

When you run this package, you should see something like this:

Results message

For some reason, the 50% sample never seems to contain 50% of the dinosaurs ...

 

Close this package, and say a joyful goodbye to dinosaurs for now!
