# The mean is the most important value when data is scattered, without a typical pattern. The mode may identify several values that occur frequently, and the median may be skewed if there are a lot of low values, but the mean catches all the values. Such patterns can occur in procurement, where costs vary according to external factors.

Mean, median, and mode are three measures of averages that show the disperse the data is from the mean or the average. These methods are used in statistics widely, whereas the mean value of the data is the most widely used method among the three.

For example, if you have the following data: 1, 1, 1, 1, 1, 1, 2, 2, 4 The median is another form of an average. It usually represents the middle number in a given sequence of numbers when it’s ordered by rank.

To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. Mean, median, and mode are three measures of averages that show the disperse the data is from the mean or the average. These methods are used in statistics widely, whereas the mean value of the data is the most widely used method among the three.

### The purpose of the mean or median (or mode) is to provide a one number summary of a set of data. The whole idea of the mean is actually quite tricky, as you can read in one of my early posts about explaining what the mean is. Generally the summary value is used to compare with another sample or population.

However if you are very sure that your data is not skewed at all and has near perfect bell shaped distribution, you can use mean. But mind you median in this case too won't be too off from mean. When should I use the mean and when should i use the median to describe a distribution?

When you have a symmetrical distribution for continuous data, the mean, median, and mode are equal. In this case, analysts tend to use the mean because it includes all of the data in the calculations. However, if you have a skewed distribution, the median is often the best measure of central tendency. The median is the number that splits the data into two equal halves, with half being higher, and half lower (there are slightly more technical definitions, to deal with things like ties, and sparse data, but this will do for our purposes).

The median, on the other hand, is the numerical value which falls in the middle of a sorted number set. In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.For a data set, it may be thought of as "the middle" value.The basic feature of the median in describing data compared to the mean (often simply described as the "average") is that it is not skewed by a small proportion of This video is brought to you by EdgeAll at http://www.edgeall.com. It teaches and helps you identify if Mean, Median or Mode should be used on a given set of Mean versus Median. The term 'median' is also a common term used when describing a data set, especially among number crunchers. To calculate a median value, we look at the midpoint of a data set, or the point in a set of values where the number of values above and below are equal.
