Average absolute deviation
The average absolute deviation (AAD) of a data set is the average of the absolute deviations from a central point.
See Quadrant count ratio and Average absolute deviation
Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Quadrant count ratio and correlation are Covariance and correlation.

Guidelines for Assessment and Instruction in Statistics Education
The Guidelines for Assessment and Instruction in Statistics Education (GAISE) are a framework for statistics education in grades Pre-K–12 published by the American Statistical Association (ASA) in 2007.

Pearson correlation coefficient
In statistics, the Pearson correlation coefficient (PCC) is a correlation coefficient that measures linear correlation between two sets of data. Quadrant count ratio and Pearson correlation coefficient are statistical ratios.

Quadrant (plane geometry)
The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes.

Standard deviation
In statistics, the standard deviation is a measure of the amount of variation of a random variable expected about its mean.

Statistics
Statistics (from German: Statistik, "description of a state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Statistics education
Statistics education is the practice of teaching and learning of statistics, along with the associated scholarly research.
