Convert 7.9 million into standard value
Assume that aset of test scores is normally distributed with a mean of 100 and a standard deviation of 20 use the 68-95-99?
68% of the scores are within 1 standard deviation of the mean -80, 120 95% of the scores are within 2 standard deviations of the mean -60, 140 99.7% of the scores are within 3 standard deviations of the mean -40, 180
Test scores have a mean of 100 and a standard diviation of 20 what is the relative frequency of scores under 120?
Approx 84%.
What is the mean and standard deviation of a distribution of T-scores?
T-scores have a mean of 50 and a standard deviation of 10. These values are fixed and do not change regardless of the distribution of T-scores.
If a test score of 83 was transformed into a standard score of -1.5 and the standard deviation of the scores was 4 what is the mean?
78
If your son scored 88 in the quiz what was his percentile in the class?
Your question can not be answered. A tally of all scores in the class is necessary. These are then ranked (lowest to highest), and the percentiles identified. For more information, I suggest you look at percentiles under wikipedia.
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 is a Measure of spread about the mean?
Standard error, standard deviation, variance, range, inter-quartile range as well as measures based on other percentiles.
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.
How do you convert p-sat scores to sat scores?
you multiply it by 10
ACT scores needed to get into the University of Tennessee?
The 25-75th percentiles of the ACT are from 24-29, so a middle 20 range or onwards should be pretty safe for admission.
If standard deviation of 10 scores is 0?
All the scores are equal
How do you calculate a priori probability when you know standard deviation and mean scores?
If it is possible to assume normality, simply convert the desired score to a z-score, and look up the probability for that.
What are percentiles?
p10 eguals
How do you convert 7.9million into standard value?
