While both SCiO Lab Mobile and SCiO Lab can be used to observe data, SCiO Lab is easier to use for this purpose as the view screen is larger, and you can download your data and build models only from SCiO Lab.

Multiple views are available to observe the data:

Scan View

 Sample View

 Spectrum View

Use the scan view and check for accuracy in each scan. Use the sample view to see multiple scans of the same sample at one time.  The accuracy of your attributes is critical to the success of your model.
Use the spectrum view to look for outliers and see trends.

Once you have observed your data, the next step is to scrub it.
