2. In the plural sense, statistics means

3. ____________ is used to compare the variation or dispersion in two or more sets of data even though they are measured in different units.

4. _________ is used to the criterion of consistency i.e for consistent performance

5. If $\beta_2=\frac{m_4}{m_2^2}<3$, the distribution is called
