what is the z-score for a raw score if 89?
To determine the z-score for a raw score of 89, you will need the mean and standard deviation of the distribution. The z-score is a measure of how many standard deviations a given score is from the mean.
To obtain the z-score, you can use the formula:
z = (X - μ) / σ
Where:
- X represents the raw score (89 in this case)
- μ represents the mean of the distribution
- σ represents the standard deviation of the distribution
If you have the mean and standard deviation, simply substitute the values into the formula to calculate the z-score.
