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 deviation
Standard deviation is the unit measurement. This tells what the value a decimal is.
Look at the parallelogram below. <1 and <3 are each 35 degrees. What is the measurement of <2?
It would be a nominal level of measurement. Each choice would be unique but there is no value attached to them
Each axis is labeled with the name of the variable, the unit of measurement, and a range of values.
Technically is an ordinal level measurement - because the options imply a hierarchy (i.e low to high levels of your variable of interest), but we cannot say that the difference between each level is precisely the same as you would be able to with an interval measurement. There is some controversy over this though, and it is still often used like an interval measurement in statistical tests, although this might not really be appropriate.
I think you are going for continuous variable, as compared with discrete variables.
gives a standardized unit that tells how far away each measurement is from the mean
You'll want to look up variance and standard deviation.
It is difficult to say that the rules of lacrosse are standardized. Each league and age group has slightly different rules and each group was set up at different times.
For a standardized variable, each case's value on the standardized variable indicates it's difference from the mean of the original variable in number of standard.
Several observations are taken for each measurement to eliminate or decrease the margin of error.
Each chemical element has a standardized chemical symbol, not a formula.
Each grammar school test will be a little different depending on the subject, the teacher, and the school. Standardized tests are tests given to all students of a certain grade to see how they are doing. Don't be scared if everyone tells you the test is hard.

Every state has a different standardized test, so each state is different.

The measurement of 2 in the parallelogram when 1 and 3 are each 35 degrees is 145 degrees.
The volume of a cube with a measurement of 3.5 on a side is 42.875.
