Why is it so easy for rating to go down but not back up??

In a word, Walkersm nailed it.
It takes 5 times as many 5 star ratings to make up for one 1 star rating.
As with everything Uber: Do The Math.
Take 3 typical P/T days of 10 rides each day:
nine rides get 5 stars
one ride gets 1 star
If the next day you ten rides and two are 4* and eight are 5*one ride gets 1 star
(9*5=45) + (1*1=1) = 46
46 score / 10 rides = 4.6 rating
46 score / 10 rides = 4.6 rating
your overall rating will drop again to 4.3
If the next day you manage to get ten 5 star ratings( (2*4=8) + (8*5=30) = 40 ) + 48 = 86
86 score / 20 rides = 4.3 rating
86 score / 20 rides = 4.3 rating
your rating for the three days would only climb to 4.53
(10*5=50) + 46 + 40 = 136
136 score / 30 rides = 4.53
136 score / 30 rides = 4.53

Michael needs to work on his math a little bit:

Day 1 at 4.6 is correct. But Day 2 is 48, and adding 48 to the 46 from Day 1 equals 94 (not 86) for a rating of 4.7. Adding in Day 3 of 50 gives a total points of 144 and a rating of 4.8.
But the premise is correct, it is all in the math. Think about it as DISTANCE. There is a range of 1 star to 5 stars. When your rating is above 4.5, there is only a "distance" of .5 to move up but a "distance" of 3.5 to move down. The more "distance" a number can move, the 'easier' it is to move that direction. If you had 100 rides and an rating of 4.9, one more 5 star ride and you rise to 4.91, but 1, 1 star rides drops you to 4.87, because the 'distance' from your 4.9 down to 1 is GREATER than the 'distance' from 4.9 to 5. The other night I made 13 trips. I got 12 5 stars and a 1 star, with the 1 star being my highest fare of the evening. My 1 star rider was a first time passenger who spoke very little English. It is my belief that she thought 1 star was the best as she told me she was "pleased" with the ride (in very broken English). So instead of me getting a 5.0 star for the previous day, I get a 4.92. Currently, I am at 5.0 for 1 Day, 4.95 for 7 days and 4.85 for 30 days, with over 100 rides. Raising that 30 day is TOUGH with over 100 rides in the equation, there is only a 'distance' of .15 to the maximum of 5 stars.

Right but not so right!
I believe Uber deactivates and invites you to take the training after your last 100 rated trips drop below 4.60.
It was mentioned in another thread. Somebody with 4.85 dashboard rating was facing deactivation and taking the class.

When discussing ratings with pax, I always tell them " if 1 out of 10 people consistently rated me a 4 star, all else rated me 5 star, I will lose this job!" And they get very interested and surprised.
I ask them to please rate all their Uber drivers responsibly knowing this fact.

UberXTampa, excellent video. For you sports nuts, when I say "distance", let's look at a batting average in baseball. The best possible is to bat 1,000 (ie. 10/10). But in Baseball, anyone who bats .300 is considered a very good batter. So let's say our player is 30/100 for an average of .300. At his next at bat, he gets a hit and is now 31/101 which is .30693. But if he does not get a hit, he is 30/101 or .29702. Getting a hit raised his average almost 7 points but not getting a hit drops him only 3 points. That is because the "distance" between .300 and 1.000 is GREATER than the distance between .300 and zero.

Do any of them call you out on this? I'm guessing not but you never know.

I expected this from this board!
No, no one called me on this.
People know no math.
It is Florida, we cannot even count votes.
This is another ub eR math, except it is spread by some drivers

UberXTampa, I always ask the passenger if it was "A Five Star Ride." If it wasn't, I ask what was wrong with it. My only problem with that is when I get a Non English speaking passenger. My first week, I asked nothing and just let them rate me. My very first passenger wasn't even my passenger, it was his brother. So the person who got to rate me was never in my vehicle. I am sure all of us have had weird experiences and some negative with the rating system. I vary from 4.85 to 4.95 so I am not worried, but I see where some changes would be beneficial. I think that Uber should throw out the TOP 10% and BOTTOM 10% once you get to 500 rides, just to weed out those who do not know how to use the star system, or who were never in the vehicle, or who were drunk, etc.......

If someone has a rating of 4.60 (or below) after 100 rides... that means that approximately 40% out of those 100 rides were rated less than 5 stars (it would be lower rating if some of those ratings were 3 stars or less)... that's quite a few non-5-star rides out of 100.
40% of 500 rides = 200 rides

Or 10 out of 100 people rated you 1 star out of 5 stars.
Work surge in University neighborhoods and the kid taking a ride that totals a $5.20 on a 1.2x surge will rate you a 1 star.
It is very easy to get those 1 stars.
I have been avoiding teh areas that I got 1 stars. No international students, no drunk students, no drunks back frmo bars, night clubs, no surge fares...

It means at least 10% of the riders are not happy.
Based on experience, riders rate 1 or 5. Rarely ever anything in between.
That's why, I assume 10% of riders rating me low can cause me to get 4.6 rating.
I think it is not true
because more than 20% of your rider never rate you after you finish your 100 trips
I am about to finish my 100 trips, and already figure out at least 20 people did not rate me
that is one thing make driver suck..missing ratings are never count eventhough they are possible all 5 stars

I just had three straight weeks of my weekly partner report saying above 4.8 and 'above average', yet my average went down, go figure.
I HATE with utter CONTEMPT the rating system.
Too many times a difficult rider will rate you unfairly, or you'll get a four, where the rider thinks
it's a decent rating, yet it drags your average down.
UBER is mind-bogglingly stupid to allow this to continue, because it causes STRESS and driver stress
is not good for business, in the long run.

You're assuming all 100 people rated you. Bad assumption. You could have been rated by just two people, one of whom gave you 5 stars and the other 4, which would give you a 4.5 average.

Where are you seeing the individual ratings?
You're ignoring a couple of obvious points in your wild assumption that people only give 1 or 5. Most people, if there was something they were slightly unhappy with, are more likely to give you a 3 or a 4 than a 1. The other thing that should be obvious is that since Uber doesn't define what the ratings mean, many people don't know that 5/5 is supposed to be the norm. That's pretty irrational, really. It would be perfectly logical for a rider to assume that a good driver is worth 4 stars and 5 stars is for something incredible.
If you were asked to rate a movie from 1-5, how many movies would get 5 stars? Probably not very many.
The whole thing is insane if 4.5 out of 5 is considered unacceptably low. That's the same as 90/100, which is an A in most schools. Imagine a class where 90% is a failing grade.
