What does constants variable mean in science?

A constant variable is one that is not the independent variable (the one you are changing) or the dependent variable (the one you change). Constant variables are so named because in order for the experiment to be legitimate, it is expected that the scientist control them, thus keeping them constant across all trials. This ensures that changes in the dependent variable are only the result of changes in the independent variable.

Is stars shining an example of s continuous variable?

No, it is a continuous process but not a continuous variable. The magnitude of star-shine, across all stars is a continuous variable. The magnitude of a star's shine over time is a continuous variable.


What does test variable mean?

A Test Variable(s): The variable whose mean will be compared to the hypothesized population mean (i.e., Test Value). You may run multiple One Sample t Tests simultaneously by selecting more than one test variable. Each variable will be compared to the same Test Value. In simple terms, a variable represents a measurable attribute that changes or varies across the experiment whether comparing results between multiple groups, multiple people or even when using a single person in an experiment conducted over time.


What is the difference between heterogeneity and homogeneity in statistics?

Homogeneity means that the statistical properties of the variable which is being studied remain the same across the population. Heterogeneity means that they do not: it could be that the mean changes between different subsets of the population or the variance does.


How to calculate the resistance to step down DC voltage?

Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.


Is it possible to apply voltmeter across a variable resistor?

Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
