is a tape measure the same as a ruler
Tape measure A tape measure or measuring tape is a flexible ruler and used to measure distance.
Dividend yield Its reciprocal is the Price/Dividend ratio.
Standard deviation Let X be a random variable with mean value Î¼:
Opisometer The instrument is most commonly used to measure the lengths of roads, rivers and other line features on maps. Opisometers designed for this purpose provide scales reading the measured distance in kilometers and miles.
Standard deviation This means that the standard deviation is equal to the square root of the difference between the average of the squares of the values and the square of the average value. See computational formula for the variance for proof, and for an analogous result for the sample standard deviation.
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
