How do you calculate a priori probability when you know standard deviation and mean scores?

If it is possible to assume normality, simply convert the desired score to a z-score, and look up the probability for that.

What is the probability that parents will bear five sons and no daughters?
that all depends on which facts you acknowledge as a priori state for this situation.
Define conditional probability with an example?
there are 3 types of conditional probability: 1. the indicate: if antecedent happens, then evidence manifests itself example -> when tossing a coin, if it lands on tails, then you win the game 2. the subjunctive: if antecedent would happen, then evidence would manifest itself example -> when a coin was tossed, if it would have landed on tails, i would have won the game it is recommended for optimal bayesian inferences that your a priori distribution is indicative. If not, you could be dealing with inproper, uninformative, or hyper priors, which make decision-making and posterior determination more complex, if even possible. Posterior distributions could very well be subjunctive. Suppose i have won the game, i could have tossed tails, but i could also have tossed heads.
Would a small deviation in an experiment mean that something is wrong with the experiment?
Not necessarily. It might mean that the experiment has a highly stable outcome. You need to evaluate if that is true or if the experiment is flawed. It comes down to theoretical expectations versus experimental outcomes - you should know a priori (before the fact) what to expect, so you can know if the results are good. For instance... If you were measuring the radioactivity of a sample with a relatively low count rate using a detector that recorded counts in each second, you would expect a poissen distribution. If you were measuring the same sample with a detector that counted for 1 minute, you would expect a more gaussian distribution. If, on the other hand, you were measuring the wavelength of a red laser, you would expect that every single observation would give you the same results, within an extremely tight distribution.
What is the difference between Supervised and unsupervised methods in data mining?
Unsupervised Learning• The model is not provided with the correct resultsduring the training.• Can be used to cluster the input data in classes onthe basis of their statistical properties only.• Cluster significance and labeling.• The labeling can be carried out even if the labels areonly available for a small number of objectsrepresentative of the desired classes.Supervised Learning• Training data includes both the input and thedesired results.• For some examples the correct results (targets) areknown and are given in input to the model duringthe learning process.• The construction of a proper training, validation andtest set (Bok) is crucial.• These methods are usually fast and accurate.• Have to be able to generalize: give the correctresults when new data are given in input withoutknowing a priori the target.
How do you calculate standard deviation without a normal distribution?
You calculate standard deviation the same way as always. You find the mean, and then you sum the squares of the deviations of the samples from the means, divide by N-1, and then take the square root. This has nothing to do with whether you have a normal distribution or not. This is how you calculate sample standard deviation, where the mean is determined along with the standard deviation, and the N-1 factor represents the loss of a degree of freedom in doing so. If you knew the mean a priori, you could calculate standard deviation of the sample, and only use N, instead of N-1.

What is the experimental probability of rolling a 3?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling a 3 is 1 in 6, or about 0.1667, but the experimental probability changes every time you run the experiment
What is the experimental probability of rolling an even number?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling an even number is 3 in 6, or 1 in 2, or 0.5, but the experimental probability changes every time you run the experiment.
