Which is better median or average?

Median is determined by ranking the data from largest to smallest, and then identifying the middle so that there are an equal number of data values larger and smaller than it is. ... Under these circumstances, median gives a better representation of central tendency than average.

What is the difference between median age and average age?

The median is the midpoint in an ordered list of values — the point at which half the values are higher and half lower. ... Given this group, the median of 11 is a much better representation of the typical age than the average of 15.9. That's what makes median such a useful statistical measure.

What does the median tell you?

WHAT CAN THE MEDIAN TELL YOU? The median provides a helpful measure of the centre of a dataset. By comparing the median to the mean, you can get an idea of the distribution of a dataset. When the mean and the median are the same, the dataset is more or less evenly distributed from the lowest to highest values.

Is Median considered an average?

What is the median? 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.

What is the median of 23?

Since there are an even number of values, the median will be the average of the two middle numbers, in this case 23 and 23, the mean of which is 23.

What is the median useful for?

The mean value of numerical data is without a doubt the most commonly used statistical measure. Sometimes the median is used as an alternative to the mean. ... Just like the mean value, the median also represents the location of a set of numerical data by means of a single number.

Is Median another word for average?

Some common synonyms of median are average, mean, and norm. While all these words mean "something that represents a middle point," median applies to the value that represents the point at which there are as many instances above as there are below.

What is the fastest way to find the median?

Finding the median in O(n log n)

The most straightforward way to find the median is to sort the list and just pick the median by its index. The fastest comparison-based sort is O(nlogn) , so that dominates the runtime.

What is the world's median age?

The global average median age was 29.6 years in 2015 – half of the world population were older than 29.6 years, and half were younger. Japan had the highest median age at 46.3 years. The youngest was Niger at 14.9 years.
