Definition/Meaning | Word/Phrase |
---|---|

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 |
