  • The Three Stooges

  • As a group, in show business for almost 50 years.

  • Made 190 “shorts” with Columbia Pictures.

  • Had their third short, Men in Black (1934), nominated for an Academy Award.

  • Had 4 different people in the role of “the third Stooge.”

  • Were the first to lampoon Adolph Hitler, in You Nazty Spy (1940).

Statistical Tests


Slide10 l.jpg

The Nature of Statistics

  • In a nutshell, the nature of a statistical test is:

  • to hypothesize a certain relationship within a population or between two or more populations,

  • to take a random sample from the population(s), and

  • to calculate the probability of the random sample(s) being drawn when the hypothesis is assumed to be true.

The desired outcome is to get the probability from (3) which is small. In this event, the hypothesis is rejected in favor of its alternative.


Slide11 l.jpg

The Hypothesis


Slide12 l.jpg

From: http://www.threestooges.net/

“To [Joe] Besser’s eternal shame, he had it written into his contract that he would not be subject to slapping or bodily harm.”

“Pure Slap Shtick” by Richard von Busack, Metro Santa Cruz, January 16-22, 1997. Available online at: http://www.ratical.org/ratville/3stooges75yrs.html


Slide13 l.jpg

“Moe and Larry – they were the best. I enjoyed every minute of it with them. In fact, to show you how wonderful they were, I never liked to be hit with anything. And Larry used to say to me ‘don’t worry Joe, I’ll take it.’ Now that’s the kind of guys they were.”

From Stooges: The Men Behind the Mayhem, (DVD) Mackinac Media, 2004.


Slide14 l.jpg

The null hypothesis is:

H0: "The average number of violent acts by Moe against Curly per episode is the same as the average number of violent acts by Moe against Joe."

The alternative hypothesis is:

Ha: "The average number of violent acts by Moe against Curly per episode is greater than the average number of violent acts by Moe against Joe."


Slide15 l.jpg

Since we suspect that the average for Curly is greater than the average for Joe, we perform a one-tailed test.


Slide16 l.jpg

But First, an Example of a Statistical Test


Slide17 l.jpg

From:http://www.dvdbeaver.com/film2/DVDReviews33/3_stooges_collection_vol._1.htm

From:http://lunkhead.net/stoogepics/mls/stoogepics2.html

We have no (stated) reason to suspect that there is a difference between the amount of Moe-instituted violence towards Curly versus the amount of Moe-instituted violence towards Shemp.

For the sake of illustration, we test a null hypothesis concerning this.


Slide18 l.jpg

Since we have no reason to suspect a difference between the amount of violence from Moe to Curly or from Moe to Shemp, we test for a difference and perform a two-tailed test. This gives the following null and alternative hypotheses:

H0: "The average number of violent acts by Moe against Curly per episode is the same as the average number of violent acts by Moe against Shemp."

Ha: "The average number of violent acts by Moe against Curly per episode is different than the average number of violent acts by Moe against Shemp."


Slide19 l.jpg

Since we have no reason to suspect a difference between the amount of violence from Moe to Curly or from Moe to Shemp, we test for a difference and perform a two-tailed test.


Slide20 l.jpg

Five RANDOMLY selected Shemp episodes and five RANDOMLY selected Curly episodes were chosen. The number of acts of violence by Moe to these Stooges is as follows:

Shemp

Curly

Episode (episode #) # of acts

Episode (episode #) # of acts

Average: x1 = 13.2

Average: x2 = 9.6


Slide21 l.jpg

The sample standard deviation, s, of a sample of size n is:

This yields the following sample standard deviations and variances from our data:

Shemp

s1 = 4.9670 s12 = 24.7

Curly

s2 = 2.3022 s22 = 5.3


Slide22 l.jpg

The two sample t-test assumes that samples are taken from a normal distribution. Given the means and standard deviations of our samples, this is a reasonable assumption.

The t statistic for this data is calculated as:

From the above data, we have:

t = 1.470


Slide23 l.jpg

Since we have no reason to suspect a difference between the amount of violence from Moe to Curly or from Moe to Shemp, we test for a difference and perform a two-tailed test with t = 1.470.


Slide24 l.jpg

Excel gives a p-value for this data of:

p = 0.1920.

This means that we could reject the null hypothesis, but only with confidence

(1- p) x 100% = 80.80%.


Slide25 l.jpg

Conclusion?

A level of confidence of 81% is generally considered insufficient (with the “industry standard” level of confidence set at a minimum of 95%). This means that we should fail to reject the null hypothesis that the means are the same. This does not mean that we accept the null hypothesis, but that we find the data insufficient to give a conclusive decision.

Slide26 l.jpg

Now, You Gather the Data


Slide27 l.jpg

Five RANDOMLY selected Curly episodes and five RANDOMLY selected Joe episodes were chosen. The number of acts of violence by Moe to these Stooges is as follows:

Curly

Joe

Episode (episode #) # of acts

Episode (episode #) # of acts

The plus signs (+) indicate that the data for these episodes are incomplete. You will complete these data sets soon.


Slide28 l.jpg

We now watch 3 to 5 minute segments of some of the randomly chosen shorts to fill in the missing data.

We want to count every act of violence of Moe towards Curly, and Moe towards Joe.

Joe

Moe

Curly


Slide29 l.jpg

A Bird in the Head

Columbia short number 89, costarring Curly.

This short is classic Stooges and has the boys wallpapering a room.

Sock-A-Bye Baby

Columbia short number 66, costarring Curly.

A baby is abandoned on the Stooges’ doorstep, and they prepare a meal and diaper change.

Space Ship Sappy

Columbia short number 178, costarring Joe.

The Stooges act as “sailors” on a spaceship to Venus.


Slide30 l.jpg

We now use Excel to compute the mean, variance, t-statistic, and p-value for our collected data.


Slide31 l.jpg

Our data yields a p-value of: 0.00xx

Therefore, we reject the null hypothesis:

H0: "The average number of violent acts by Moe against Curly per episode is the same as the average number of violent acts by Moe against Joe"

And accept the alternative hypothesis

Ha: "The average number of violent acts by Moe against Curly per episode is greater than the average number of violent acts by Moe against Joe."

With confidence (1-p) x 100% = 99.xx%

Nice!

Why, Soitenly!

Slide33 l.jpg

Possible Problems

  • What counts as an act of violence?

  • Sample size?

  • Data is normally distributed?

  • Episodes are independent?

  • Lengths of films are all the same?

  • Other?

Please fill out a questionaire!

From:http://www.lunkhead.net/

Thank You!


Slide37 l.jpg

What about Shemp versus Joe?


Slide38 l.jpg

Five randomly selected Curly episodes and five randomly selected Joe episodes were chosen. The number of acts of violence by Moe to these Stooges is as follows:

Shemp

Joe

Episode (episode #) # of acts

Episode (episode #) # of acts

Average: x1 = 13.2

Average: x2 = 3.6


Slide39 l.jpg

The sample standard deviation, s, of a sample of size n is:

This yields the following sample standard deviations and variances from our data:

Shemp

s1 = 4.9670 s12 = 24.7

Joe

s2 = 0.8944 s22 = 0.8


Slide40 l.jpg

The two sample t-test assumes that samples are taken from a normal distribution. Given the means and standard deviations of our samples, this is a reasonable assumption.

The t statistic for this data is calculated as:

From the above data, Excel gives:

t = 4.251


Slide41 l.jpg

Excel give a p-value for this data of:

p = 0.0066.

And so we can reject the null hypothesis with a confidence of

(1- p) x 100% = 99.34%.
