What is the formula in getting Mean Percentage score?
The formula for calculating the mean percentage score is to first add up all individual scores, then divide the total by the number of scores. This will give you the mean score. To convert the mean score to a percentage, you would then divide the mean score by the total possible score and multiply by 100. This will give you the mean percentage score.
How do you find the z score of 12.5?

What is a z-score?
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.
what is the definition of a z score for individual values What does its sign indicate?
A z-score measures how many standard deviations an individual value is from the mean of a dataset. It is calculated by subtracting the mean from the individual value and then dividing by the standard deviation. A positive z-score indicates that the value is above the mean, while a negative z-score indicates that it is below the mean. A z-score of zero means the value is exactly at the mean.
What does it mean if the Z score of a test is equal to 0?
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
Is a negative z score always an indicator that the raw score is below the mean?
Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.
What does a positive Z-score mean?
it means that the score is above the mean

How do you find the mean from raw score z score and standard deviation?
To find the mean from a raw score, z-score, and standard deviation, you can use the formula: ( \text{Raw Score} = \text{Mean} + (z \times \text{Standard Deviation}) ). Rearranging this gives you the mean: ( \text{Mean} = \text{Raw Score} - (z \times \text{Standard Deviation}) ). Simply substitute the values of the raw score, z-score, and standard deviation into this formula to calculate the mean.
Is it true any score with value less than the population mean will have a negative z-score?
Yes. If a score is below the mean, the z score will be negative.
What does a negative z-score mean?
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.
Calculate the z-score for a test score of 87 if the mean test score is 81.1 and standrd deviation is 11.06?
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.
