Unispins for Statistics Project. (Need Your Help)

sutton629 · 2008-01-16T18:56:39+00:00

Well I have to say thank you for looking and I need some help. For my final Project in my AP Statistics class I have to do a project in an area of interest to me. Of course I chose unicycling and now I must collect some data over a period of time and I need some help. I am going to be calculating the overall probablity of landing unispins. My project is not possible without your help. If over 25 days you will do 10 of each unispin you can do (ex. if you can do 5spins then 10 540 spins, 10 360spins, and 10 180 spins.) Record the number of spins that you land (ex. 01/14/08 180-8/10, 360-3/10) A log over 25 days is what I need in order to make this experiment work. You do not need to start right away but it will be a good way to help you learn your spins. This is not a judge of your riding so it helps if the data is honest because it is the long term numbers that help this project. I will be posting a log format up soon but it is simple enough to make your own. I am hoping to get several riders as to make this a successful project. Thank you for your time and I will keep you posted. -Kevin -- sutton629 'Myspace' (http://www.myspace.com/sutton629) ------------------------------------------------------------------------ sutton629's Profile: http://www.unicyclist.com/profile/15900 View this thread: http://www.unicyclist.com/thread/67032 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- ** SPEED ** RETENTION ** COMPLETION ** ANONYMITY ** ---------------------------------------------------------- http://www.usenet.com

hmmm... I don't know much about statistics, but as people have different
abilities, wouldn't the results of this project tell you the general
ability of the unicycling community instead of the "probability of
landing unispins".
in other words, the probability of landing unispins is completely
dependent on the ability of the rider (and the surface they are riding
on, mood, weather, clothing, concentration etc)
this probably doesn't make any sense, but oh well :p

Can I unispin for Jesus instead? 😄

Maybe not even that. Aren't people that actually can unispin more
likely to participate? Before I could unispin, trying 2 or 3 times a
day could be frustrating enough--often ending with awkward landings
and/or slamming parts of my legs into parts of the unicycle.
Also, there needs to be a more precise definition of "landing" a
unispin. Does that mean both feet are on just the pedals and/or
cranks? Does that mean you can ride out of it? Does unispin have a
formal definition already? (I'm too lazy to try to look it up.)

yeah, it's certainly biased that way. I would participate but 25 rows
of 10 zeroes probably isn't going to help him get the stats he wants.
(but if it is, then i'm happy for my data to be used!)

I think it would be a better statistic project if you did the public's
responses to unicycling.
just go out to a mall or someplace crowded and start unicycling. See
how many negative responses you get compared to positive responses
compared to neutral responses. then do it based on percieved age and
sex.
some british guy did a study like this over a couple years.

You can apply statistics to this but your results will be so variable
that your Chi^2 (or whatever test you use) value will be much higher
than your critical value making the information sort of useless. Adding
an some more constraints to who participates might help. How about
people who have previously never successfully landed a unispin. I am
sure there are many people in that group that just need some sort of
incentive to go out and do it.
By narrowing your search you may limit your results but you are more
likely to get a meaningful statistic, and give people a reason to learn
a new skill.
I have never attempted a unispin before but I might give it a try in
the name of science.

Haha thanks but the information that I am trying to gather is about the
long term probabilities. I will have to do many things for my project
and it is all about the long term numbers but is rather complicated to
explain. The skill level is also a factor that I will work with as I
look at all the data.
I also like the idea of recording the reactions. So for those not
interested in doing unispins and you ride then information about
peoples responses will also be fun information to calculate. If you
ride regularly please keep a log of the positive and negative responses
that you receive. Positive meaning a nice comment, smile, or a jolt of
a friend and a pointing. Negative being dumb comments or ignoring. A
well organized log over about 25 rides would help very much. Please
also post the region that you are from.
Thank you for your well thought comments and I hope that several people
will be able to pitch in and help or else this project will not be
possible. I will not be able to present on Unicycling and will end up
with a dull depressing project if I do not collect any data.

I'm not trying to be mean or rude, but have you talked to your teacher
about your ideas for this project?
It seems like your procedure has a few flaws statistically speaking.
I'm not sure how picky your teacher may be, but my stats professors
would have probably said it was not a scientifically sound test.

my teacher was cool with the idea and liked it but the response is not
so positive so i think that this thread should be locked and die out
because the response is not so great. people would rather say that it
is flawed then let me use the information for my class. I will probably
have a simple online questionare up soon that I think should be a bit
more friendly to those that are actually willing to help. I appreciate
those that did try to help.

I'd be glad to help, but I also agree that the data you're collecting
wouldn't give much meaningful information.
What exactly are you trying to test and what do you want to predict
with it? Do you have a hypothesis?
