Dependent variables are one of three types of variables used in scientific experiments. Learn about the difference between dependent, independent, and control variables, and see how variables interact in an exa
Give an example of a testable hypothesis with an independent and dependent variable which you operationally define. Hypothesis: Exercise improves memory. (a) What is the independent variable? (b) What is the dependent variable? Which of the following describes dependent variables in an...
学术研究:识别变量(identify variables)是研究起点,验证假设(verify hypotheses)是核心步骤。 四、如何避免混淆?情境化选择建议 优先使用'identify'的场景: 需要确认身份、归属或特征时,例如:“The system can identify faces in real time.” 表达心理认同时,例如:“She identifies with en...
A screening experiment for the formation of alginate gels with eight variables like sodium alginate (3–5 g/100 g), calcium orthophosphate (1.5–2.5 g/100 g), glucono-δ-lactone (GDL) (1.5–2.5 g/100 g), pineapple juice (0–78 g/100 g) and sugar (0–12 g/100 g) and gel-...
The variables that are kept the same are the ___. shape of the container You are planning an experiment to find out whether the rate at which water freezes depends on the shape of the container. What is the independent variable? rate at which...
The first objective was to determine if there were variables that uniquely characterized consistent, occasional, and infrequent seat belt users. An operational definition was developed to define these user groups, and this definition was used in an exploratory analysis to determine if and how the ...
This phrase is used when you want to specify the action of identifying variables without implying any particular set of variables. Examples: The first step is to identify the variables that have an impact on the outcome. Researchers aim to identify the variables that influence the experiment resul...
Statistical analysis. Univariate analysis was used to analyze categorical variables with a Chi-square test and continuous variables with the Mann-Whitney U test. Hardy-Weinberg equilibrium (HWE) among the controls was evaluated using Fisher's exact test. SNPs with monomorphism and significant HWE...
To identify those exons whose inclusion strongly co-varies with their gene dependencies across cancer cell lines, we fitted a linear model for each exon using exon inclusion and gene expression as variables to predict Demeter2 gene dependency scores. To associate these datasets we could only conside...
Celiac disease (CeD) is an immune-mediated disorder that develops in genetically predisposed individuals upon gluten consumption. HLA risk alleles explain 40% of the genetic component of CeD, so there have been continuing efforts to uncover non-HLA loci that can explain the remaining heritability. ...
