1.3.1. Measures a single basic concept

1.3.2. Split-Half methods Single test is used to make two shorter alternative tests

2.1.2. Not numeric

2.2. Criterion-related

2.2.1. Concurrent Deals with measures that can be administered at the same time Numeric

2.2.2. Predictive Determines how well the test predicts future behavior Numeric

2.3. Construct
