Test Frequency DistributionItem Difficulty and Discrimination: Quintile TableInterpreting Item StatisticsReferencesPart II of the Item Analysis program displays a test frequency distribution. The raw scores are ordered from high to low with corresponding statistics: 1. Standard score: A linear transformation of the raw score that sets the mean equal to 500 and the standard deviation equal to 100; in normal score distributions for classes of 500 students of more the standard score range usually falls between 200 and 800 (plusSee more on citl.illinois.eduAI Workflow: Data Analysis and Hypothesis Testing | Analysis Exploratory data analysis is mostly about gaining insight through visualization and hypothesis testing.
