formula of mean median mode
Answers
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
Mode Formula
The mode is the most frequently occurring value. Like the statistical mean and median, the mode is a way of capturing important information about a random variable. Formula for mode of grouped data: Mode = L + (fm−f1)h/ = L + (fm−f1)/
A distribution in which the values of mean, median and mode coincide (i.e. mean = median = mode) is known as a symmetrical distribution. Conversely, when values of mean, median and mode are not equal the distribution is known as asymmetrical or skewed distribution.
