Mean-Mode=3(mean-Median)

anonymous · Answer

The mean, median and mode are averages. The mean is calculated by adding up all the numbers and dividing by how many there are or $\frac{\sum_{i=1}^{n}x _{i}}{n}$ if you're familiar with sigma notation. The median is the middle value when the data is put in size order. The mode is the most common value.


The range is the difference between the biggest and smallest values in a data set.

the mean, median and mode are all measures for describing how scores clusters together. They are three different measures for the centre of a set of scores. So they are called 'measures of central tendency'

mean = sum of the scores divided by the number of scores

median is the middle score after the scores are arranged in order

mode is the score that occurs the most
