statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables analysis of variance , ANOVA
mathematics branch dealing with limits, differentiation and integration of functions of variables calculus
statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation) coefficient of correlation , correlation , correlation coefficient
experiment designed to control for variables affecting the results of another experiment control experiment
either of two correlated variables correlate , correlative
statistics, simultaneous change in value of two random variables in correlation
two-way tabulation of the relations between correlates; row headings are the scores on one variable and column headings are the scores on the second variables and a cell shows how many times the score on that row was associated with the score in that colu correlation table
statistical relation between two or more variables such that systematic changes in the value of one variable are accompanied by systematic changes in the other correlation , correlational statistics
use of statistical correlation to evaluate the strength of the relations between variables correlational analysis
any correlation in which the rates of change of the variables is not constant curvilinear correlation , nonlinear correlation , skew correlation
relation between variables when the regression equation is nonlinear (quadratic or higher order) curvilinear regression
statistical factor designed to remove the effect of inflation; inflation adjusted variables are in constant dollars deflator
sum of the exponents of the variables in the term degree of a term
part of calculus that deals with the variation of a function with respect to changes in the independent variable (or variables) by means of the concepts of derivative and differential differential calculus , method of fluxions
(statistics) a variable whose values are independent of changes in the values of other variables experimental variable , independent variable
numerical scale used to compare variables with one another or with some reference number index
function of two variables i and j that equals 1 when i Kronecker delta
mathematical technique used in economics; finds the maximum or minimum of linear functions in many variables subject to constraints linear programming
relation between variables when the regression equation is linear: e.g., y linear regression , rectilinear regression
(logic) a word (such as `some' or `all' or `no') that binds the variables in a logical proposition logical quantifier , quantifier
