What word tells how many standard deviations a measurement is away from the mean?
z-score
How many standard deviations a measurement is away from the mean?
The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
What is the probability of randomly selecting values more then 2.57 standard deviations away from the mean in either a positive or negative direction in a normal distribution?
1% total 0.5% in either direction
How can we assess differences in quality or performance by simply comparing z values under a standard normal curve?
z value looks at standard deviations away from the mean. if its tests scores, a higher positive z value means they are higher away from the mean in a positive direction the opposite is true for a negative z score.
What do you do if you get a number that is not on the Normal Distribution table as it is too high so above 3?
Oh, dude, if you've got a number that's off the charts and not on the Normal Distribution table because it's like, way too high, you can just say it's like, super rare or extreme. Just pretend it's a celebrity at a regular person party - they stand out, but they're still part of the crowd, you know? Just acknowledge it's a statistical outlier and move on with your life.
