This category contains examples of Data Coding.
Data coding is a technique for simplifying manual arithmetic.
It is also useful for reducing rounding errors when using a computer.
When calculating an mean or standard deviation, the following two rules can be used:
- $(1): \quad$ If each datum is multiplied by a constant $b$, then the mean and standard deviation are each multiplied by constant $b$
- $(2): \quad$ If a constant $a$ is added to each datum, then the mean is increased by $a$ but the standard deviation is not affected.
