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 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

The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.

That would be the z-score.z = (measurement - mean) / standard deviation

z score

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.

It depends what you mean by how long are mares, if you mean by how long they live the same as the average horse or pony, how long they are by measurement it varies to which breed they are.

You measure a great number of them, keeping records of every measurement, and then you calculate the average of all of the measurements.

If he shows other signs that he likes you he probably likes you.

You'll want to look up variance and standard deviation.

LB, or lb means "pound" in measurement.

It shows us by telling us how far away it is from the mean.

MPV is an acronym for mean platelet volume. The MPV is a measurement of the average size of platelets. A high MPV usually means that there is good platelet function.

It means he is angry or scared. You should try to calm him, but if he shows signs of attacking, shut him away or completely ignore him. Hope you find this helpful! :-)

The mean is an average so, just add all the items you are trying to find the mean for and then divide by the number of items. Example 1+2+3= 6/3=2. 2 is the mean

Be more specific, what do you mean by quartz?: Are you talking about the quartz in side an atom? A unit of measurement? Or possibly a type of rock?
