An empirical relationship exists between mean, median and mode. For a moderately skewed distribution it is: If a…
The value which has a higher frequency than others in its neighborhood is called mode. The important characteristic of mode…
When the observations are arranged in ascending or descending order, the value which divides them into two parts is called…
There is a Mathematical relationship between arithmetic mean, geometric mean, and harmonic mean. This relationship is given as: …
The harmonic mean of a set of observations is the reciprocal of the arithmetic mean of the reciprocal of the…
Geometric mean is defined only for non-zero positive values. Therefore in order to use geometric mean all the observations must…
Following are some of the important properties of arithmetic mean, which are elaborated with the help of simple problems. Problem:…
If all the values of the data are not equally important, a weighted arithmetic mean is calculated after assigning appropriate…
In case of frequency distribution the raw data is arranged by intervals having corresponding frequencies. So if we are interested…
Arithmetic mean is the sum of the values divided by the number of values in the raw data. Arithmetic mean…
