Running head: DESCRIPTIVE STATISTICS FOR MODERN SCORE DISTRIBUTIONS 1 Descriptive Statistics for Modern Test Score Distributions: Skewness, Kurtosis, Discreteness, and Ceiling Effects
Many statistical analyses benefit from the assumption that unconditional or conditional distributions are continuous and normal. Over fifty years ago in this journal, Lord (1955) and Cook (1959) chronicled departures from normality in educational tests, and Micerri (1989) similarly showed that the normality assumption is met rarely in educational and psychological practice. In this paper, the a...

According to the types of variables, which consist of qualitative and quantitative variables, some descriptive statistics have been introduced. Frequency percentage is used in qualitative data, and mean, median, mode, standard deviat...
متن کاملDistributions of Hardy-Weinberg equilibrium test statistics.
It is well established that test statistics and P-values derived from discrete data, such as genetic markers, are also discrete. In most genetic applications, the null distribution for a discrete test statistic is approximated with a continuous distribution, but this approximation may not be reasonable. In some cases using the continuous approximation for the expected null distribution may caus...
متن کاملDescriptive statistics.
Statistics is a science that provides precise techniques for collecting and sorting information made easy by tools and methods for further analysis. The object of descriptive statistics, from sample data, is to describe the most important characteristics, by which we refer to those amounts that provide information on the topic of interest which we are studying.
متن کاملLinking U . S . School District Test Score Distributions to a
In the U.S., there is no recent database of district-level test scores that is comparable across states. We construct and evaluate such a database for years 2009-2013 to support large-scale educational research. First, we derive transformations that link each state test score scale to the scale of the National Assessment of Educational Progress (NAEP). Next, we apply these transformations to a ...
