Item Analysis. Item Analysis is an important (probably the most important) tool to increase test effectiveness. Each items contribution is analyzed and assessed. To write effective items, it is necessary to examine whether they are measuring the fact, idea, or concept for which they were intended.
ABC Analysis: A classification of items in an inventory according to importance defined in terms of criteria such as sales volume and purchase volume. ABC Classification: Classification of a group of items in decreasing order of annual dollar volume or other criteria. This array is then split into three classes called A, B, and C. The A group represents 10 to 20% by number of items, and 50 to 70% by projected dollar volume. The next grouping, B, represents about 20% of the items and 20% of the dollare volume.
