what is the meaning of equidistant in mathematics
Equidistant A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal.[1]
Continuous or discrete variable A continuous variable is one which can take on infinitely many, uncountable values.
In situ In chemistry, in situ typically means "in the reaction mixture."
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.
