The Geometric mean is a special types of average where we calculate the root of the product of a value of a set of observations. It is usually used to define various types of growth rates such as population growth, interest rates…
The harmonic mean is the inverse of the arithmetic mean of the reciprocals of the observations of a set. It is a type of average generally used for numbers that represent a rate or ratio such as the precision and the…

Regression analysis is a statistical technique that develop a relationship between explanatory (independent) variable and response (dependent) variable.

Interclass correlation and intra-class correlation are two special cases of correlation analysis. Interclass correlation shows the association among the groups and intra-class correlation shows the association within a group. Intra class(a) vs Inter class(b) “Interclass” means among the groups. “Intra…
Population vs sample in statistics are plays two different role in statistics. Population is the whole study area where sample is the required study area from the whole study area. Population vs Sample-statistical aid Population vs sample Population Population indicates…
