The DAT test specifications of the Quantitative Reasoning Section listed on the official DAT Test Guide lists the following topics (verbatim) to be tested on the QR section:

Mathematical Problems - Algebra (equations and expressions, inequalities, exponential notation, absolute value, ratios and proportions, and graphical analysis); Numerical calculations (fractions and decimals, percentages, approximations, and scientific notation); Conversions (temperature, time, weight, and distance); Probability and Statistics; Geometry; and Trigonometry

Applied Mathematics (Word) Problems

Okay so the algebra and numeric calculations seem straightforward enough. But what about statistics and probability? Does anyone know the scope of statistics covered on the DAT? Will there be things like random variables, probability distributions, mean, median, etc. that are typically seen in a statistics class? Does the probability that's tests include counting (like permutations and combinations)? And what is the scope of the trig and geometry covered on the DAT?

On this forum, it also appears that Math Destroyer and CDM are among the top resources used to prepare for the section. If you had to pick just one of them to use to prepare for the DAT, which one would it be and why?
