The "z-score" is derived by subtracting the population mean from the measurement and dividing by the population standard deviation. It measures how many standard deviations the measurement is above or below the mean. If the population mean and standard deviation are unknown the "t-distribution" can be used instead using the sample mean and sample deviation.
a line of best fit, on a graph you draw the line where it is closest to most points and measure how far it is away from the line. http://www.bbc.co.uk/schools/gcsebitesize/maths/images/graph_53.gif
Deviation, actually called "standard deviation" is, in a set of numbers, the average distance a number in that set is away from the mean, or average, number.
Deviation and absolute deviation are two other measures.
Z-Score tells how many standard deviations a measurement is away from the mean.
gives a standardized unit that tells how far away each measurement is from the mean
Youth get carried away by the television shows on these days.
The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
The Moon is, on average about 238,000 miles away from the Earth.
you shouldn't. they will run away.
That would be the z-score.z = (measurement - mean) / standard deviation
Lightyears (for example, the nearest star to our sun is 4.1 lightyears away).
Mostly the measurement of change, or difference. (eg, you can't be -10 feet away from something, if you move forward 10 feet you're abs(10) feet away, if you move back 10 feet, you're abs(-10) feet away.) Mostly the measurement of change, or difference. (eg, you can't be -10 feet away from something, if you move forward 10 feet you're abs(10) feet away, if you move back 10 feet, you're abs(-10) feet away.)
Are you certain that the fact is true? What statistics have you?
A scientist might estimate a measurement because they do not have the ability to measure something right away. They may not have the tools or the means to measure accurately.
Any measurement you wish. If you want to know how far away the Andromeda Galaxy is, then see the related question.
the Z score, or standard score.
Given that there are 5,280 ft. in 1 mile, how many miles away is a gas station that is 103,762 ft. away
Standard deviation determines how far away the data values are from the average.
Standard deviation is a measure of the spread of data around the mean. The standardized value or z-score, tells how many standard deviations the measurement is away from the mean, and in which direction.z score = (observation - mean) / standard deviationStandard deviation is the unit measurement. This tells what the value a decimal is.
