They should be.
Of course!
When putting the scores in, you use the normal distribution graph, which is the best start.
You calculate the z-scores and then use published tables.

Yes those are wonderful scores. It is usual.to get a 9 at 5 minutes after birth
Of course!
If the distribution is Gaussian (or Normal) use z-scores. If it is Student's t, then use t-scores.
z-scores are distributed according to the standard normal distribution. That is, with the parameters: mean 0 and variance 1.
If the standard deviation of 10 scores is zero, then all scores are the same.
When putting the scores in, you use the normal distribution graph, which is the best start.
Normal IQ scores for children typically fall between 90 and 110. Scores above 130 are considered superior, while scores below 70 are indicative of intellectual disability. It's important to consider other factors when interpreting IQ scores, such as a child's age and individual strengths and weaknesses.
You calculate the z-scores and then use published tables.
They are said to be Normally distributed.
None.z-scores are linear transformations that are used to convert an "ordinary" Normal variable - with mean, m, and standard deviation, s, to a normal variable with mean = 0 and st dev = 1 : the Standard Normal distribution.
True or False, One major advantage of transforming X values into z-scores is that the z-scores always form a normal distribution

99.7% of scores fall within -3 and plus 3 standard deviations around the mean in a normal distribution.
