How to Find the Median (With Formula, Examples, Merits and Demerits)
Article shared by
Median is the middle value in a distribution. It is a positional average. Median divides the data into equal halves, wherein 50 percent of the values lie below the median and 50 percent of the values lie above the median. Before determining the middle value, the observations have to be arranged in an ascending or […]
How to Find Mode in Statistics (With Examples, Formula, Merits & Demerits)
Article shared by
Mode is the value that occurs with the greatest number of frequency. For example- if the given set of values are 2, 3, 2, 4, 5, 2, 3, 1, 6 the mode here would be 2 which appears thrice. However, when there are 2 or more values appearing with same frequencies then the mode is […]
Relationship between Mean, Median and Mode | Statistics
Article shared by
In this article we will discuss about the relationship between mean, median and mode. Distribution of statistical data shows how often the values in the data set occur. A distribution is said to be symmetrical when the values of mean, median and mode are equal. That is, there is equal number of values on both […]
