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 is similar to the Pareto principle in that the 'A' items will typically account for a large proportion of the overall value but a small percentage of number of items. Example of ABC class are. â 1 Aâ items â 20% of the items accounts for 70% of the annual consumption value of the items.hus, the inventory is grouped into three categories (A, B, and C) in order of their estimated importance. 'A' items are very important for an organization. Because of the high value of these 'A' items, frequent value analysis is required.
