Variable:某物或某人的某一特征和其他个体不同。 quantitative variables:定量变量either discrete(可以被数)or continuous.(A continuous variable is a variable whose possible values form some interval of Numbers)Typically, a continuous variable involves a measurement of something, such as the height of a ...
A variable which is not measurable on a continuum or represented in a quantitative relation to a scale—e.g., race, sex. Qualitative variables fit into discrete categories based on their attributes. Segen's Medical Dictionary. © 2012 Farlex, Inc. All rights reserved. ...
some kind of math (like addition), it’s not qualitative — instead, it’s aquantitative variable. For example, you can’t add blue + green (unless you’re in an art class — even then you “mix” them, you don’t add them!) — making “blue” and “green” qualitative variables...
Transform a quantitative variable into a qualitative variable
A moderator refers to “a qualitative (e.g., gender, race, class) or quantitative (e.g., level of reward) variable that affects the direction and/or strength of the relation between an independent or predictor variable and a dependent or criterion variable” (Baron & Kenny, 1986). ...
Variable activity and clause connectivity are often considered as qualitative and quantitative metrics to model clause-variable dependencies.译文:变元活跃度和子句连接性通常被认为是对子句变量依赖进行建模的定性和定量度量。 Activity of a variable (or literal) is defined as the number of its occurrence am...
Unique to the perspective of self-organized dynamical systems is its focus on qualitative change, places where behavior bifurcates. The reason is that qualitative change affords a clear distinction between one pattern and another, thereby enabling one to identify the key pattern variables that define...
Qualitative (or categorical) variables are discrete; that is, a measurement consists of assigning an observation to one or more categories. The attributes of the variable consist of the finite set of potential categories. The set of categories must be mutually exclusive and collectively exhaustive. ...
Objective: To assess quantitative and qualitative differences in water components between normal bone marrow and reactive hematopoietic marrow in aplastic anemia using magnetic resonance (MR) spectroscopy with variable echo times (TEs). Design: Water content, T2 value of the water component, and signal...
1) quantitative and qualitative variable system 定性与定量变量系统1. Based on the fuzzy quantitative theory, a practical method in the high-test quantitative and combined with the quantitative and qualitative variable system has been proposed in this paper. 在研究模糊数量化理论的基础上 ,力图找到...
