Question

Tough riddle for the bored people >:))

(admins..this is just for fun hehe)

@Ishaan94 's teamwork score is 75; his Problem Solving score is 93; his Engagement score is 71, yet his SmartScore is 99.

@FoolForMath 's teamwork score is 71; his Problem Solving score is 82; his Engagement score is 70, yet his SmartScore is 99.

@Callisto 's Teamwork score is 66; her Problem Solving score is 76; her Engagement score is 65, yet her SmartScore is 86.

radar's teamwork score is 68; his problem solving score is 75; his engagement score is 70, yet his SmartScore is 86

@Diyadiya 's teamwork score is 67, her problem solving score is 69; her engagement score is 69, yet her SmartScore is 76

@mimi_x3 's teamwork score is 66; her problem solving score is 69; her engagement score is 70, yet her SmartScore is 76

Create an equation on how these SmartScores were solved in terms of the Teamwork, Problem Solving and the Engagement.

Answer 1

Nice Problem - intriguing!

Answer 2

Hint: this has nothing to do with mean/average

Answer 3

hmmm i think this is the hardest riddle so far

Answer 4

But the formula is not given..its a secret..

Answer 5

@lgbasallote Just curious... do you have an answer?

Answer 6

Why was I in your question /_\ ?

Answer 7

maybe u can do a regression on this data to figure out the formula....

Answer 8

uh oo

Answer 9

lol @Callisto i was just looking at the homepage =))) @Study23 secret ;D :S

Answer 10

i agree. good question. my smartscore took a nosedive couple of days ago.. was it because it was friday the 13th?

Answer 11

lol i dont think smartscore was born that time :P the nosedive was because of the tweakings..they are increasing the difficulty of the criteria..the question would just be to create an equation hehe

Answer 12

well, if you have the answer; give us a hint..

Answer 13

lol no i dont know :)) im curious too...i think fool has a clue to this so i posted this to challenge him =))

Answer 14

lol, posting a riddle that you don't know the answer of..

Answer 15

im entitled to ask questions i dont know as well :P lol

Answer 16

then don't call it your riddle :P

Answer 17

better? :P

Answer 18

hmmm more info may help...

Answer 19

This algorithm is supposed to be a secret, and I'm not revealing it! xD

Answer 20

Lol, you know it? :P

Answer 21

"Yes, yes, the moderators consider me so special, they presented the formula to me on a golden tray!"


Ofcourse, I Don't!!

Answer 22

I would prefer facing "Tom Riddle" rather than facing this "tough riddle", anyday lol.

Answer 23

^i'd give you a medal for that...but i'd like to reserve it to the guy who answers this :P

Answer 24

hmm..are you able to use a software to work it out?

Answer 25

i wish we are able to use systems to figure it out @_@

Answer 26

Hmm who has same smartscore but different teamwork,problemsolving and engagement? except the ones with 99.

Answer 27

This is definitely not a linear function.

Answer 28

.Sam. and phi have the same smart score and same problem solving but diff teamwork and engagement

Answer 29

We 'll do something. We 'll feed raw data from SmartScores of a thousand people into a program and see if it cracks it.

But now that I think of it, there's more to it than just those 3 scores. (may be our activity, no. of replies per question (testing diligence) and host of other factors).

Answer 30

I think dumbcow can solve it. :D He is really good at stats.

Answer 31

my guess would be collect a large sample and run a huge regression with 3 independent variables

Answer 32

Diya and Mishi too!! same smart score, and problem solving.

Answer 33

Trick questions.... all admins hack their accounts so they can have 99.

Answer 34

callisto -> radar same smart score..different everything

Answer 35

well, i think that there is something wrong with the profile thing I doubt that I have answered 900 questions..

Answer 36

Yeah there is bug.

Answer 37

the 3 parts will have different weights, i think problem solving is weighted the heaviest
there may be some unknown constants in the formula that would be hard to determine
of course they may be tweaking the formula all the time as well :P

Answer 38

Problem Solving->99 => Question answered > 3k.

Answer 39

Look at his medals ^

Answer 40

there may also be some unknown variable that is not mentioned... a Dumbscore for doing stupid things?

Answer 41

uh, like what i just did....

Answer 42

Akshay got only 1 medal

Answer 43

lol hmm their system is buggy, I don't think we can determine the algorithm as of now.

Answer 44

Maybe we should go back to the old system...

Answer 45

wow lol =)) pretty sure a former guru shouldnt have those counts :P

Answer 46

It was much more difficult to get higher score with old system. that's how it should be

Answer 47

BTW anyone who can help me with linear algebra?!

Answer 48

lol romero..this is soo hard believe me =)) i can get 1 level per day back then..now i cant

Answer 49

ok after regression, using sample of 8 scores

S = 0.74P + 0.2T + 0.22E

R square was .99 but p-values were high so coefficients are insignificant
anyway its gives a rough formula
S = smartscore
P=problem solving
T =teamwork
E = engagement

Answer 50

Akshay might be the only member whose smart score is less than the other three parameters. I think the new system is based on activity not some actual algorithm. Because lgb has 81 and he is quite active but akshay isn't active, he might not have answered question in weeks. Same is with Jhonny9 he is active a lot on the site. nikvist isn't active much as he only solves the challenging the problems, so he got ranked low, despite the fact he is one of the best problem solvers on OpenStudy. Recently even phi has been very active so he got ranked higher.

Answer 51

I am saying while the rest of the parameters like engagement, problemsolving and teamwork might have an actual algorithm. The overall smart score is highly influenced by your activity on the site.

Answer 52

Better hide something here lol. Again here are the stat

Answer 53

good point Ishaan
in that case there is no tangible correlation and doing regression is pointless

Answer 54

but the activity is in the parameters right? it's under the teamwork...

Answer 55

Ishaan be cool dude !

Answer 56

If the system were only accounting for the three parameters, your score would never have exceeded the parameter's score.

Answer 57

hmmm good point...so there is something they're not telling us -__- lol

Answer 58

yeah @Ishaan94 huge emphasis on activity, am guessing.

Answer 59

Wait, if I don't log in for few days/months, will my smartscore decrease drastically?

Answer 60

There's a lot more than what meets the eyes.

Answer 61

I guess so, @Callisto

Answer 62

yes @Callisto smartscore is based kind of like bassed on how you you stand against the others..so if you become inactive then others will go up and you'll go down..kind of like that..yeahhhh i knew how it works :p lol

Answer 63

So what's the use of having higher SS now ? If its gonna drop down if you stay away from OS for few days :D

Answer 64

Hmm That's coool~ Then I just don't log in for a long while and I'll score 0, right ?

Answer 65

score ps tm eng
score 1.00
ps 0.89 1.00
tm 0.86 0.88 1.00
eng 0.13 -0.02 0.44 1.00

if anyone is interested her is a correlation matrix
seems engagement doesn't really effect much

Answer 66

yeah it doesnt..it's the hardest tolevel up...@Callisto yeah but that'll be a very looooong time

Answer 67

My point too exactly, @Diyadiya . Obviously activity should be take into account, but to what extent? If someone's not active for an year, will it sink him to nil? How do our 'employers' see that?

Answer 68

inactivity -> engagement -> hardest to level up/down

in regards to leveling down...i heard that if people overtake you, your level will go down..i think

Answer 69

well that was fun

everyone remember these scores don't really mean that much, just like the medals
its all about helping people with math and/or getting help :)

Answer 70

I agree. :-)

Answer 71

yes :DDD

Answer 72

Agree three!! =]
