A perfect example of how theories are tested ! Theory predicts the outcome of the experiment, and the purpose of the experiment is to test the theory. If the outcome of the experiment is appreciably different from the one predicted by the theory, (and if the experiment itself was valid), then the prediction is flawed, and the theory must be either tweaked or trashed.
It is the result that you think will happen as the outcome of an experiment. It is the same as the "expected result", which is usually denoted as E(x)=xp(x).
Experiment cannot be predicted in advance is RANDOM EXPERIMENT...... set of all possible outcomes. outcome that can be predicted with certainity. when an experiment performed repeatedly- called trial. Ex. If a coin is tossed,we can't say,whetefr head or tail will appear .so it is a Random Experiment. Sample Space:-- Possible outcomes of a random experiment.. set of all posssible outcomes.. denoted by--- "S". and no. of elements is denoted by n(s). ex. In throwing a dice ,the number that appears at top is any one of 1,2,3,4,5,6 ,So here: S= 1,2,3,4,5,6 n(s) --- 6
It is the result of the experiment. It is the value of the observation.
It can, but need not, affect the outcome of the experiment variable.
It is what you expect to happen before you actually carry out the experiment, based on the knowledge and theory you already have and know. *called a hypothesis
Based on previous research in similar conditions, it is predicted that the experiment will produce results that support the hypothesis. However, unexpected variables could influence the outcome, so the prediction is not definitive.

A hypothesis is an educated guess at what the outcome of the experiment will be. This means that the information must be tested to see if the predicted outcome is true or false, and there must be the possibility that it is can be proven false.

How to determine the number of outcome in an experiment ?
A dependent variable is a variable in an experiment or study that is measured or observed to see how it is affected by changes in the independent variable. It is the outcome or response that is being studied or predicted.
A scientific theory or hypothesis must be able to make predictions that can be tested. It must be possible to design an experiment so that there is one outcome if the hypothesis is true and a different outcome if it is false. This is what is meant by saying that a hypothesis is testable or falsifiable. If such as experiment is carried out and the outcome is not as predicted then the hypothesis must be rejected and replaced by an alternative hypothesis - or a modified version.
If the hypothesis is supported in an experiment, the expected outcome or result predicted by the hypothesis will likely be observed. This would provide evidence to validate the hypothesis and support the initial reasoning or explanation provided.
It is the result of the experiment. It is the value of the observation.
