If you're studying thegrowth rateof plants using differentfertilizers, can you identify the variables? Start by thinking about what you are controlling and what you will be measuring. The type offertilizeris the independent variable. The rate of growth is the dependent variable. So, to experimen...
The Null Hypothesis:This is ahypothesisstating the experimental treatment will have no effect on the participants or dependent variables. It's important to note that failing to find an effect of the treatment does not mean there is no effect. The treatment might impact another variable the resear...
Two important types of variables in all types of math and science (shout-out to the science-lovers!) are independent variables (IV) and dependent variables (DV). As with many math terms, there are several names for each of these types of variables that can be used interchangeably. Let's...
Graphing independent and dependent variables follows a standard method in which the independent variable is plotted on the x-axis and the dependent variable on the y-axis.
Although scientists typically only change one independent variable at once, there may be multiple dependent variables or results of the experiment. Another type of variable is called the controlled variable. These are the facets of the experiment that are kept the same. This is to ensure that ...

We start with some set of possible time-dependent phenomena and we represent, mathematically, this set just as interacting concepts depending on simultaneous observations but possibly with only an implicit notion of time flow, and we then show that there exists a privileged—or canonical—time flow...
An independent variable is one of the two types of variables used in a scientific experiment. The independent variable is the variable that can be controlled and changed; the dependent variable is directly affected by the change in the independent variab
Some of the hidden variables of the second kind will be carried by the photons from their creation in the atom toward the polarization filters. The hypothesis of hidden-variables theories of the second kind is that, when a photon reaches a polarization filter, the angle of the filter's ...
