It means that there is a probability of 0.0968 that an observation as extreme as this occurred purely by chance.
It means that the observation was 1.3 standard errors away from the mean. The probability of getting an outcome as extreme as this, in both directions, is 0.19, approx.
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
Z score of 0 is the mean of the distribution.
z score is defined as z = (x-mean)/sd, where mean is the mean of the sample (or population) and sd is the standard deviation of the sample or the population. x is the raw score. z-score standardizes the data. The standardized data will have a zero mean and unit variance. It has numerous applications in statistics.
z-score of a value=(that value minus the mean)/(standard deviation)
For z-score calculation, mean and std deviation must be given.
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
z score = (test score - mean score)/SD z score = (87-81.1)/11.06z score = 5.9/11.06z score = .533You can use a z-score chart to calculate the probability from there.

Yes. If a score is below the mean, the z score will be negative.
A z score of -1.3 means that the score is located at the negative 1.3 sigma level with respect to the mean.
it means that the score is above the mean
Z score of 0 is the mean of the distribution.
A z-score of 0 means the value is the mean.
z-score of a value=(that value minus the mean)/(standard deviation). So a z-score of -1.5 means that a value is 1.5 standard deviations below the mean.
Z is the Z-score. See related link.
