Mean, Median and Mode
What are the mean, median, and mode?
Mean, Median and Mode are the measures of central tendency. These three measures of central tendency are used to get an overview of the data. They represent the true essence of the given data set.
What is the relation between mean, median, and mode?
The relationship between mean median and mode is:
Mode = 3 Median – 2 Mean
How to find mean, median, and mode?
Mean, Median, and Mode of any given data set is calculated using the suitable formulas which are discussed above in the articles.
How to find the mean?
Mean is also called the average, it is calculated for ungrouped data using the formula:
- Mean = (Sum of observations)/(Number of observations)
In case of Grouped Data, the mean is calculated by the three methods
- Direct method
- Assumed mean method
- Step deviation method
How to find the median?
Median is the middle term of the data when it is arranged in either ascending or descending order. It is calculated using the formula:
- Median = (n + 1)/2th observation {when n is odd}
- Median = Average of (n/2)th and [(n/2) + 1]th observations {when n is even}
How to find the mode?
Value with the highest frequency is called the mode. Mode is calculated by observation first the given set of values is arranged in either ascending or descending order then the value with the highest frequency is noted as Mode.
Mean, Median and Mode
Mean, Median, and Mode are measures of the central tendency. These values are used to define the various parameters of the given data set. The measure of central tendency (Mean, Median, and Mode) gives useful insights about the data studied, these are used to study any type of data such as the average salary of employees in an organization, the median age of any class, the number of people who plays cricket in a sports club, etc.
