Intervening variables link the independent and dependent variables, but as abstract processes, they are not directly observable during the experiment. For example, if studying the use of a specific teaching technique for its effectiveness, the technique represents the independent variable, while the comp...
It answers questions to justify relationships with measurable variables to either explain, predict, or control a phenomenon. Types of quantitative methods include: Survey research Descriptive research Correlational research LEARN MORE: Descriptive Research vs Correlational Research Remember, it is only ...

A variable is naturally dichotomous if precisely 2 values occur in nature (sex, being married or being alive). If a variable holds precisely 2 values in your data but possibly more in the real world, it's unnaturally dichotomous. Creating unnaturally dichotomous variables from non dichotomous ...
Control Variables Control variables are not the primary focus of the research, but they are properties that researchers need to monitor because they can influence the outcome. Failure to incorporate them into a study can bias the findings. To prevent this bias, scientists can either hold these ch...
In discussing learner variables and strategies, we have to keep in mind the arbitrary nature of actually identifying these aspects. As the existing research point out, it is not possible to observe directly qualities such as aptitude, motivation and anxiety. (Oxford, 1986). We cannot lo...
Once simulation software has calculated your 2D or 3D design’s response to those forces, it presents a simulation analysis. The analysis is the mathematical data extracted from the calculations made, repurposed into a report that contains areas of concern or necessary improvement. ...
What is systematic observations in biology? Explain how genotypes and phenotypes of the parents and offspring can be related to the independent and dependent variables. What process is responsible for the independent assortment of alleles? What observation is explained by the Law...
Still, as impressive as all this is, it may be trivial compared with what comes next. 出自-2016年12月阅读原文 So what other variables could be used if the racial concept is thrown out? Yudell said scientists need to get more specific with their language, perhaps using terms like ancestry ...
