Lounge effect on your rating

Dave Astle · 2006-04-04T19:38:48

After reading an assertion earlier today that people who frequently post in the Lounge have higher ratings than those who do not, I asked Michalson to run a few queries on the database to see if there is any validity to that claim. What follows is the report which he provided to me, which I think some of you will find interesting. Beyond what is discussed in the report, I also looked at the data for the top 50 highest rated members, and found the following:On average, 38% of their posts have been in the Lounge. In fact, if I sampled any 5 of them sequentially based on their rating, the average Lounge post percentage (LPP) only varied by a point or two 10 of them have a LPP of less than 10% Only 15 of them have a LPP over 50%. Only 3 of those people are in the top 20. I then looked at the 50 lowest rated members, and found the following:They have an average LPP of 65% 5 of them have a LPP of less than 10% 36 of them have a LPP over 50%. 17 of them were over 90% (with 7 at 100%). Based on these observations, and the more extensive analysis described in the report, there seems to be no evidence to support the notion that frequent Lounge posting will improve your rating. If anything, the opposite seems to be true. On to the report. The sample was created by examining posts made after the rating system was introduced. The 10,000 most active users were chosen (since they were most likely to have been seen and rated), excluding staff, moderators and the anonymous poster. The first graph shows the percentage of a user's posts in the lounge compared to their average rating. Posters on the extreme left have never seen the lounge (0% of posts in the lounge), while posters on the extreme right always post in the lounge (100% of posts in the lounge). The vertical shows the average rating of posters in a given percentile. As you can see there is a correlation between where the users post and what their rating is – those who post in the technical forums have stable ratings higher than 1000. Those who post in the lounge seem to receive both more positive and more negative ratings, resulting in a wide degree of variation, and many more extreme positive and negative ratings. Next we see the number of posts overall, compared with the user's average rating. The position (1 to 99) is the percentile of their number of posts compared to the rest (this way the data is spread out, rather then compacted to the low post count side of the chart). Users in the 99th percentile (right side) are those with thousands of posts. You can see that as the number of posts increases, the rating also increases right from the start. Next we see the same graph, but only counting posts in the lounge. Here posts in the lounge do not have any measurable effect on ratings up until the 85th percentile. At the 90th percentile, there is suddenly a rapid jump in ratings that extends about 100 points past the high reached by regular posters. The same two graphs can also been seen as pure data. First all posts, then lounge posts. Again we see that when comparing post count to rating we get a smooth curve, while the lounge post count to rating correlation is almost non-existent (though percentage seems to as seen in the very first graph).

This topic is a trap. Whenever you answer, you increase your LPP.

I like your Humor... rating++ so you won't feel too bad - not that
I can influence it much, but for the fun of it :)

My LPP is wildly inacurate.
A couple of years back, I got really drunk one night, and went over my profile and deleted thousands of my posts and threads. You might still see some traces of replies to messages that aren't there anymore if you look back.

But I don't really post outside of lounge anyway. I don't have tech questions that can be answered in a place like this.

Wow!
Both numbers were found using the 'viewposts' script, so anything it leaves out is left out of both of them =-) Of course, that inflates the number somewhat, but I doubt by enough to put me under the 50% line. I still think my posts before a certain date somehow became detatched from my user account, but I haven't been able to find any evidence yet =-/

I have an LPP of under 1.7%. Including this post. Yeah, I'm pretty unsociable [lol] (I also believe I got rated up by Myopic Rhino because of the lounge effect!)

18 Lounge Replies out of / 325

< 5.5%
and my ratings are so low.

All I do is ask a lot of questions, and help as many people as I can.
yet, you people love to rate me down.
just for future reference: I rate down anybody for no reason.
