For a continuous variable it is 0.5 but for a discrete variable the answer depends on the probability of the variable taking the mean value. It is half of the rest of the probability.
If the discrete variable X has mean m and Prob(X = m) is p
then Prob(X > m) = (1 - p)/2.

What does the z score of 1.3 mean?
It means that there is a probability of 0.0968 that an observation as extreme as this occurred purely by chance.
In a normal distribution with mean 80 and variance 144 squared what is the probability above 100?
The probability is 0.4448, approx.
What would -2 standard deviation below the mean be?
It would mean that the result was 2 standard deviations above the mean. Depending on the distribution of the variable, it may be possible to attach a probability to this, or more extreme, observations.It would mean that the result was 2 standard deviations above the mean.

What does a negative deviation mean?
A negative deviation means that the observation is smaller than whatever it is that the deviation is being measured from.
What does fair mean from a probability perspective?
From a probability perspective fair means equal probability.
What does the standard deviation of 2.686 means if the Mean is 5.96 and the number is 699?
The observation is more than 250 standard deviations (SD) away from the mean. For a normal distribution, the probability of being more than 3 SD from the mean is 0.0027 so the probability of an observation being 250 SD from the mean is infinitesimally small.

What does covert observation mean?
An observation in which participants do not know that they are being watched. Usually high in validity.
What is the probability of the mean being greater than 78?
A very high probability if your numbers are greater than 78.
What does covert observation mean in psychology?
covert observation sociology The researcher is taking part in the activity and the people don't know they are being observe like being undercover

What does the Probability Rating of 2 mean with respect to a Probability Range?
You need a lot more information on the rating scale being used.
What is four sigma?
It could refer to four standard errors. If an observation from a Gaussian (normal) distribution is 4 standard errors away from the mean, it has an extremely low probability.
What is symmetric distribution?
It is a probability distribution in which the probability of the random variable being in any interval on one side of the mean (expected value) is the same as for the equivalent interval on the other side of the mean.
How do you do probability of independent events?
The answer depends on what you mean by "do". Does it mean calculate individually, calculate the probability of either one or the other (or both), calculate the probability of both, calculate some function of both (for example the sum of two dice being rolled)?
What is unsystematic observation mean?
casual observation
