First off, we reject the null hypothesis of independence: education level and marital status are associated, χ 2 (12) = 23.57, p = 0.023. Because they are rankings rather than percentages, per- centiles should be viewed as approximate rather than spe- cific values. What skills did the reading test measure? Interpreting Statistical Measures—Class Scores Mathematics Task Suggested Use This mathematics task is intended to encourage the use of mathematical practices. Other information, such as grades, teacher feedback and scores on other tests will help determine your child's academic strengths and needs. In this lesson, we'll learn how to interpret the results of percentile calculations. There are many methods of interpreting the results of spirometry tests. Your score benchmarked against a group of pre-tested candidates. (they ranked the lowest out of 100) Ex.

To guide and monitor their admission processes, many LSAT score users use information about the percentage of test takers who earn each scaled score. Differences in COPD classification have been shown in population data sets when using fifth percentiles as the lower limit of normal (LLN) vs the current GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines of FEV1/FVC < 0.70 for detecting airway obstruction and an FEV1 of 80% predicted for detecting and classifying the severity of COPD (GOLD/PP). Using 15 as the percentage tuberculin response cut-off for interpreting a QFT test as positive identifies approximately the same number of persons compared with using a TST induration cut-off of 10 mm.

A percent-correct score represents the percentage of questions a test taker answered correctly on a test. For example, if a test taker answered 20 out of 50 questions on a test correctly, then his or her percent-correct score would be 40%. The raw score, in this example, is 20. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another.
