data analyses - interesting newspaper article using Median (what your name tells about your age!!)
Gurumurthy K
When we started looking at names based on data extracted by SocialCops from Delhi’s voter rolls, we were particularly drawn to the relationship between ages and names. One great example of work on this is by data journalism pioneers Fivethirtyeight.com. On similar lines, there is quite a lot you can say about someone's age based on their name in Delhi too.
For this, we looked at the ages of all people with a given name, and
calculated their median age. The median is the age of the mid-point of
the distribution, meaning that you’d find half of all people with that
name on either side of the median. The median Delhi voter is 37 years of
age, so looking up your name gives you a good idea of whether your name
is more popular among younger people or older people.
