Are negative zscores lower than positive zscores?
Of course!
What kind of graph would you use to show the scores?
When putting the scores in, you use the normal distribution graph, which is the best start.
How do you to get the probability in normal distribution?
You calculate the z-scores and then use published tables.
What is an analysis in which scores of individuals on one variable are used to predict the scores of the same individuals on another variable?
reporcoal
Are these apgar scores within normal limits 8 at 1 minute and 9 at 5 minutes after birth?
Yes those are wonderful scores. It is usual.to get a 9 at 5 minutes after birth
Are negative zscores lower than positive zscores?
Of course!
When to you use a z scores or t scores?
If the distribution is Gaussian (or Normal) use z-scores. If it is Student's t, then use t-scores.
How do you find normal distribution of z-scores?
z-scores are distributed according to the standard normal distribution. That is, with the parameters: mean 0 and variance 1.
What are normal IQ scores for children?
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.
If the standard deviation of 10 scores is 0?
If the standard deviation of 10 scores is zero, then all scores are the same.
What kind of graph would you use to show the scores?
When putting the scores in, you use the normal distribution graph, which is the best start.
How would you characterize the distribution of scores in a normal distribution?
They are said to be Normally distributed.
How do you to get the probability in normal distribution?
You calculate the z-scores and then use published tables.
What is one advantage of transforming X values into z-scores?
True or False, One major advantage of transforming X values into z-scores is that the z-scores always form a normal distribution
What role do z-scores play in the transformation of data from multiple distributions to the standard normal distribution?
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.
What percentage of scores in a normal distribution would fall between z-scores of 1 and -2?
3
What percentage of scores fall within -3 and plus 3 standard deviations around the mean in a normal distribution?
99.7% of scores fall within -3 and plus 3 standard deviations around the mean in a normal distribution.
