Why is it that a that a statistical test never proves with absolute certainty that and observed outcome was not a chance result?
A statistical test assesses the probability of observing a result under a specific null hypothesis, but it cannot eliminate all uncertainty. This is because statistical tests rely on sample data, which inherently contains variability and randomness. Furthermore, a statistically significant result does not account for other potential factors or biases, meaning that while a result may be unlikely due to chance, it is not definitively proven as a non-random outcome. Thus, conclusions drawn from statistical tests are probabilistic rather than absolute.

What is the meaning of the word likelihood?
In statistics, a likelihood function (often simply likelihood) is a function of a statistical model. The likelihood of a set parameter values, given outcomes x, is equal to the probability of those observed outcome.
How do you work out the relative frequency?
The relaive frequency of a particular outcome or event is the number of times the outcome is observed divided by the total number of outcomes observed.
What is the purpose of distributing?
A probability distribution links the probability of an outcome in a statistical experiment with the chances of it happening. Probability distributions are often used in statistical analysis.

What test provides a statement of probability that experimental outcome was due to random variation?
statistical testing
Is it possible to predict the outcome of chance events?
No, it is not possible to predict the outcome of chance events with certainty, as they are inherently random and unpredictable.

How should the measure of risk of an asset be interpreted?
Risk is necessary in the investment world. The absolute measure of risk is the standard deviation which is a statistical measure of dispersion. The distribution curve shows how much an asset can deviate from its expected outcome.
What are the research project tools for analyzing the outcome?
Mathematical tools such as statistical analyses.
What does probability level mean?
The probability level for an outcome is the probability that the outcome was at least as extreme as the one that was observed.
What the difference between a pie and tartlet?
The treatment effect is the difference between the observed outcome and the "normal" outcome
What is the difference between sowing and planting?
The treatment effect is the difference between the observed outcome and the "normal" outcome

What is statistical data?
Statistical data are numbers that are based on a sampling of a population to predict an outcome. The accuracy depends on the sample number and error and confidence and other analysis.
