Statistical Tests
In a nutshell, the nature of a statistical test is:
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.
The Nature of Statistics
The Hypothesis
“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
From: http://www.threestooges.net/
“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.
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."
Since we suspect that the average for Curly is greater than the average for Joe, we perform a one-tailed test.
But First, an Example of a Statistical Test
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.

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."
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.
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:
Shivering Sherlocks (104) | 13 |
Love at First Bite (123) | 20 |
Three Arabian Nuts (129) | 9 |
Cuckoo on a Choo Choo (143) | 16 |
Knutzy Knights (156) | 8 |
Shemp
Curly
Average: x1 = 13.2
Average: x2 = 9.6
Back to the Woods (23) | 12 |
Three Missing Links (34) | 9 |
An Ache in Every Stake (57) | 6 |
Sock-a-Bye Baby (66) | 10 |
A Bird in the Head (89) | 11 |
Episode (episode #) # of acts
Episode (episode #) # of acts
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
The t statistic for this data is calculated as:
From the above data, we have:
t = 1.470
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.
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.
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%.
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.

Now, You Gather the Data
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:
Back to the Woods (23) | 12 |
Three Missing Links (34) | 9 |
An Ache in Every Stake (57) | 6 |
Sock-a-Bye Baby (66) | 3+ |
A Bird in the Head (89) | 3+ |
A Merry Mix Up (177) | 4 |
Space Ship Sappy (178) | 1+ |
Horsing Around (180) | 2 |
FiFi Blows Her Top (184) | 4 |
Oils Well that Ends Well (188) | 4 |
Curly
Joe
The plus signs (+) indicate that the data for these episodes are incomplete. You will complete these data sets soon.
Episode (episode #) # of acts
Episode (episode #) # of acts
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.
Moe
Curly
Joe
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.
We now use Excel to compute the mean, variance, t-statistic, and p-value for our collected data.
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%

What about Shemp versus Joe?
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:
Shivering Sherlocks (104) | 13 |
Love at First Bite (123) | 20 |
Three Arabian Nuts (129) | 9 |
Cuckoo on a Choo Choo (143) | 16 |
Knutzy Knights (156) | 8 |
Shemp
Joe
Average: x1 = 13.2
Average: x2 = 3.6
A Merry Mix Up (177) | 4 |
Space Ship Sappy (178) | 4 |
Horsing Around (180) | 2 |
FiFi Blows Her Top (184) | 4 |
Oils Well that Ends Well (188) | 4 |
Episode (episode #) # of acts
Episode (episode #) # of acts
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
The t statistic for this data is calculated as:
From the above data, Excel gives:
t = 4.251
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.
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%.
