The dependent variable is what is observed / measured in an investigation. Variables that are kept the same each time are called control variables. In a fair test, only the variable being tested is changed so that it is clear that it made a difference to the results.
Independent variables – the variable that is being changed during the experiment. Dependent variables – the variable being tested or measured during the experiment. In an...
The number of protons and neutrons in an atom. Radioactivity. Particles or energy released from the nucleus of an atom as it decays. Study with Quizlet and memorise flashcards containing terms like Element, Group, Period and others.
- Anomaly: An anomaly is an observation that differs from expectation or from accepted scientific views. Anomalies lead scientists to revise a hypothesis or theory.
- Central Limit Theorem: The central limit theorem states that with a sufficiently large sample, the sample mean will be normally distributed. A normally distributed sample mean is necessary to apply the t test, so if you are planning to perform a statistical analysis of experimental data, it’s important to have a big sample.
- Conclusion: The conclusion is your determination of whether the hypothesis should be accepted or rejected. It is one of the steps of the scientific method.
- Control Group: The control group is the set of test subjects randomly assigned to not receive the experimental treatment. In other words, the independent variable is held constant for this group.
Name the 6 changes in physical state. Evaporation, sublimation, melting, solidification, deposition, condensation. What happens when a substance is heated? Energy is added, so the substance will change from a solid to a liquid to a gas, as gaseous particles have more energy.
There are two meanings listed in OED's entry for the adjective preponderant. See ‘Meaning & use’ for definitions, usage, and quotation evidence.
Jan 30, 2020 · The dependent variable gets its name because it is the factor that is dependent on the state of the independent variable. Example: In the experiment measuring the effect of temperature on solubility, solubility would be the dependent variable.
