This way, you can have a greater degree of certainty that the final difference in heights (the dependent variable) is due to which food each sunflower received (the independent variable), not differences in sunlight or water. Why are dependent variables important? Science is messy. We like ...
When independent and dependent variables are plotted on a graph, the independent variable is usually measured along the x-axis and the dependent variable along the y-axis. For example, if you were examining the effect of sleep on test scores, the number of hours participants slept would be pl...
An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant ...
The dependent variable relies on the independent variable, meaning that as the value of the independent variable changes, then the dependent variable will change also. What is an independent variable easy definition? Simply put, an independent variable is the variable that doesn't rely on anything...
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). ...
across the whole clade, we ran an exponential diversity-dependent birth–death model, in which the whole clade’s own diversity was used as the predictor variable. As the sample size was inevitably relatively small, we ran each model for 2,000,000 iterations, sampling every 1,000 iterations....
meaning that the contributions of participants with a higher responsiveness varied more across informational cases. Responsiveness was then shown to be negatively associated with age, through an OLS regression, with age and a constant as a regressors and responsiveness as a dependent variable (with ...
with variable and sometimes minimal consequences for gene regulation9,10,11. Consequently, we are largely unable to predict gene expression patterns from DNA sequence alone12,13and it is unclear how the transcription of most human genes is regulated. Previous studies have shown that TF-binding-site...
The value of physical bases follows, of course, from the confidence (indeed the meaning) that is given to extrapolation of the relationship beyond the range of measured data. 展开 关键词: materials science aluminium creep mathematical models metals plasticity microstructure crystal structure elements ...
We also found that performance differentiates variability between subjects. As previously described, variability was quantified using the STD of each behavior, where a higher STD corresponds to higher variable behavior. Session performance of each subject was quantified as the percent of correct trials ...
