Project Hypothesis Testing by Dan Racic and Andrew Mackin

We’ve all observed our Math 5 professors and thought to ourselves “Wow! These are some attractive guys!”

Well, ok. But we wondered: What does the average undergraduate female at Dartmouth think about our very own professors?

Also, we wanted to pick something that everyone, especially our Math professors, would actually be INTERESTED IN!!!!

VS.

However, our primary GOAL was to determine, once and for all, the most attractive Math 5 professor!

This information could then be used in whatever way Professors Leibon and Rudel see fit (i.e. picking up chicks)

It was a difficult decision, but we decided that ProfessorRudel’s recent haircut would give him the edge in thiscontest.

Our Power Hypothesiswas that P=70%

We decided to test an equal number of females from each class, aiming for a total of thirty or more. We wanted to use a variety of methods to select these subjects:

We randomly selected a number of people from each facebook and blitzed them.

We interviewed random people whom we stopped in Collis and Thayer.

We went door-to-door to ten different dorms

We looked up people in the freshman year Green Books from the last four years, and we also asked random people. This is the blitz we sent out:

Subject: *Important* PLEASE READ!

hi! you have been selected at random as oneof 12 candidates in your class for a specialsurvey. me and my partner are doing a surveyfor math class and we need your help. all you have to do is look at two sets of pictures and then answer three easy questions. easy? easy. the only requirement is that you do not know personallyprofessors rudel or leibon from the math department, or myself or my partner. if you do know them or are off this term or cant do the survey, please let us know as soon as you can. if you can do it, we have received funding to give you a little something for helping us out. and we have chocolate for you.and we will come find you wherever you want usto and administer this easy, less than 2 minutesurvey. blitz back with where you will be (dorm room is probably easiest) asap if you cando it. thanks, and hope to see you,

Of course, we didn’t actually give them any candy or prizesbecause we are cheap. Our survey was put onto a PowerPoint, and we met with a total of 36 people (we talked to 38, but 2 declined). We took special care to get an equal division of years, and avoid sampling errors by running the test the same exact way each time.

This was the PowerPoint we showedto every subject….

Thank you for participating in this short survey. You will be shown two series of photographs of two different adult males in various poses. The two series will be separated by a brief ‘visual palate cleanser.’ You will have a short time to view each picture and you may not return to any picture. At the end, you will be asked a few short questions. Please answer to the best of your abilities.

Ready? Here’s Series One….

Ok, that was Series One. Time for a brief break,Prepare for a palate cleanser…

Now on to Series Two! Ready…

Ok, all done with the pictures. Take a moment to think about what you’ve seen. Only a few more questions…..

Can you tell the difference between these two men?

Have you ever seen either of these men inperson, or do you know who they are?

Assuming that you do have a preference for the looks of one of the males versus the other, did you prefer the person in the first series of photographs, or the man in the second?

Thank you very much for your time and help. Please let us know if you had any problems with this survey (i.e. understanding the questions, technical errors, etc)

Every person watched that same slide show, and whenwe tallied the results . . .

We were shocked! Both professors were almost equallyattractive. Or at least they were both chosen the samenumber of times.

We had been expecting to get something like this:

Instead, our actual results looked like this:

We were forced to accept our Null Hypothesis - there was less that 1% chance our Power Hypothesis had been correct!

After we discovered that people seemed to like themevenly (Null Hypothesis), we thought perhaps we could look at class years to draw some interesting conclusions…

Disappointingly, they were almost equally preferred along class linesas well.

So there you have it. Here are some confoundingfactors:

Though we told them the same things as far as poses, theirposes were different.

The backgrounds for the photos were different.

We had a hard time finding on campus- housed ‘04’s. So,We may have gotten a really weird sampling batch of them.

We gathered data on and around Winter Carnival Weekend,and we know for certain that AT LEAST 5-10% of subjectshad been drinking, and possibly many more had been that wedid not detect.

Despite these possible sources of error, we feel our testwas accurate.

Thank you for your time. We leave with some quotesFrom test subjects…

“Well, I guess he [Leibon] has a nice smile” - ‘06

“The second one because he looked friendlier” - ‘05

“Can I choose the duck?” - a lot of people

“He’s such a tragic figure, it’s like he’s [Rudell] looking into my soul” - drunk ‘07

“I have always been intimated by dark haired men” -’05
