Statistical Analysis

Launched Q&A site for statistics, data analysis, data mining and data visualization
At the end of beta, this site had...

7.6
questions
per day
Okay – 10 questions per day on average is a healthy beta, 5 questions or fewer per day needs some work. A healthy site generates lots of good content to make sure users keep coming back.
96%
answered
Excellent – 90% answered is a healthy beta, 80% answered needs some work. In the beta it's especially important that when new visitors ask questions they usually get a good answer.
138
avid users
1,763
total users
Okay – Every site needs a solid group of core users to assist in moderating the site. We recommend:
  • 150 users with 200+ rep (currently 138 users with 200+ rep)
  • 10 users with 2,000+ rep (currently 10 users with 2,000+ rep)
  • 5 users with 3,000+ rep (currently 8 users with 3,000+ rep)
3.0
answer ratio
Excellent – 2.5 answers per question is good, only 1 answer per question needs some work. On a healthy site, questions receive multiple answers and the best answer is voted to the top.
1,159
visits/day
Okay – 1,500 visits per day is good, 500 visits per day needs some work. A great site benefits people outside the community. Eventually, 90% of a site's traffic should come from search engines.
