Z-score calculation formula with examples?
In a certain city the mean price of a quart of milk is 63 cents and the standard deviation is 8 cents. The average price of a package of bacon is $1.80 and the standard deviation is 15 cents. If we pay $0.89 for a quart of milk and $2.19 for a package of bacon at a 24-hour convenience store, which is relatively more expensive? To answer this, we compute Z-scores for each:

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 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.

How would you calculate percentages for students marks on Microsoft Excel i?
Set up a formula that divides their actual score by the maximum score available. Then format that result as a percentage. So say they had a maximum score of 60 and they scored 45. If the 45 is in cell B3 you could put a formula in cell C3 as follows: =B3/60 In this case it would give you 0.75 which if formatted as a percentage will give you 75%. So put all the scores of students in one column and in the first cell of the column beside it, put the formula that divides their score by the maximum. Copy the formula down for all others and format them as a percentage.

If a score s equal to the mean it and z score will be?
If a score ( s ) is equal to the mean of a dataset, its z-score will be 0. The z-score is calculated using the formula ( z = \frac{s - \mu}{\sigma} ), where ( \mu ) is the mean and ( \sigma ) is the standard deviation. Since ( s ) equals ( \mu ), the numerator becomes zero, resulting in a z-score of 0. This indicates that the score is exactly at the average of the dataset.
