In stark contrast, dependent variables, also known as "responding variables," are the outcomes or responses measured as a result of changes in the independent variable. They are the "then" in the scientific hypothesis. In our plant growth experiment, the height of the ...
A fundamental part of experimentation and thus also in inquiry learning, is only varying the independent variable in order to investigate a possible effect on the dependent variable, whilst holding all other potentially confounding variables constant (or “controlled”) across experimental conditions (...
In a scientific experiment, which variable is measured rather than manipulated? (a) Independent variable. (b) Dependent variable. (c) Control variable. (d) Null variable. What are variables? In research, vari...
Mit der vorliegenden Fragebogenstudie wurde diese Annahme am Beispiel eines chemischen Experimentierlabors uberpruft. Die Untersuchung erhob bei N = 272 Schulern der Sekundarstufe 1 motivationale Variablen vor und nach dem Laborbesuch, deren Angaben mit N = 222 Schulern ein...
PID control is widely adopted in various industries to regulate an output variable by manipulating an input variable. PID control computes the control action based on the difference between the reference (or desired) glucose concentration and the measured value of the glucose concentration [9,49,50...
In science, a variable is a detail or condition that can be controlled or perhaps altered in some way. In scientific investigations, studies are designed that contain three different types of variables: dependent, independent and control.
the most effective in this case. The same weightage has been given to all the control variables; therefore, the output weights (MPC parameter) of all the control variables are 1. The value of rate weight for every control variable is 0.1. It should be noted that in case of the MPC, ...

Fig. 2: CD24-CAR-T cells target MM cells and promote macrophage phagocytic clearance in vitro. a CD24-CAR-T and MOCK-CAR-T constructs. CD24-CAR vector was constructed by CD24-specific single-chain variable fragments (scFvs), a safety switch (RQR8), and a 4-1BB co-activation domain...
The inverted pendulum is a typical multi-variable and non-linear system. It is hard to improve its performance because of modeling difficulty, parametric uncertainties during actual system operation. Iterative Learning Control (ILC) can achieve perfect tracking or performance when there is model uncerta...
