On Base Rate of Success

by Matthew Stollak on Thursday, March 14, 2013

One of my favorite terms in HR is "base rate of success."  Its also rarely discussed, but absolutely critical.

Simply put, the "base rate of success" tells us the proportion of employees who would be successful on the job if we hired randomly instead of applying some predictor.

As Gatewood and Feild (2010) write in their book "Human Resource Selection:"

If 100 percent of the applicants would be successful if hired, there is no added information provided by the predictor; one would simply randomly pick from the pool of superstar candidates.  Conversely, if every applicant in the selection pool would fail if hired, the predictor cannot help identify even one applicant who would be successful; none are successful.

We invest considerable time in our selection tools.  We apply certain assessment tests believing they provide added information that would help differentiate amongst qualified candidates.  We spend countless hours interviewing the "best" applicants hoping it will give they final impetus on who to choose.

How much better are these predictors than simply throwing darts or picking out of a hat?  Have you looked at your measures to see if they are providing you that edge?  How much would your company pay improved your ability to select by 3%? 5%? 10%?

On Absenteeism and Due Dates

by Matthew Stollak on Monday, March 4, 2013

Last Friday, I discussed my battles with absenteeism in the classroom.  Not only do students suffer in their performance by missing class, but it creates more work for me in terms of time grading poor answers on exams.

Where absenteeism poses a particular problem beyond just missing class is when assignments are due or exams are scheduled.  Students may have legitimate reasons for being absent; as a result, my policy takes into account three situations:


Homework assignments, exams, or computer work will not be accepted after the dates and times when due except from those persons:

(1)   who must attend a required school-sanctioned event (varsity sports, concert, etc.), and have provided me, one week before the event, with a letter from the instructor, coach, etc., indicating the reason such attendance is required.

(2)   who are too ill to attend class when homework is due, or the exam is scheduled, and notify me within 6 hours of the due date (i.e., no later than 3:00 p.m.).  Further, you have provided me, within one week after the illness, with a letter from an appropriate health care professional describing the illness, and its relevance to not meeting class requirements.

(3)  who have a personal problem or confront an emergency that prohibits them from attending class, contacted me within 6 hours of the emergency (i.e., no later than 3:00 p.m.), and have provided me with a letter from a credible authority, their academic advisor, or from the Dean verifying the personal problem or emergency.

Situations arise during the course of the semester that will cause me to revisit the policy and make changes.  Take this sterling example:
  • A student commutes to class from his/her off-campus home.  On the day an exam is scheduled, he/she e-mails me that his/her car has broken down and he/she will not be able to make it to class.  Per the policy, I required a note from an appropriate party - in this case, the auto repair shop.  The student provides the note, and I notice the home address of the student on the receipt.  It turns out the student's "commute" was less than a mile from a campus, and he/she could have easily walked to class.
As a result, I may have to consider adding a sentence or two about commuting to campus, including a commuting range, for the next semester.

As always, the policy is a dynamic, not static, instrument, and students will find inventive ways to find loopholes.  Sigh!


On Battling Absenteeism

by Matthew Stollak on Friday, March 1, 2013


Like most managers, I engage in a semester-long battle with absenteeism.  I have the enviable position of teaching two sections of business statistics.  Combine that with a time slot of 8:00 A.M. and/or 9:00 A.M., and you can envision the long waiting list of students at registration.

Students are over 18 and they're paying for the class, so why should I care whether or not they attend?

1) After 18 years of teaching, and thousands of data points collected, a clear picture emerges - attendance and doing one's homework matters.   After every exam, I can see a clear correlation between amount of points earned on a chapter problem set and the subsequent exam score.  At the end of the semester, I can see a clear correlation between points earned and a student's final grade.  Similarly, attendance is a predictor of success in the class.  

Over the past several semesters for a class that meets 4 times a week, 50 minutes a day, for 15 weeks:
*The average grade on a 4.0 scale for zero absences: 3.21
*Average grade for 1 absence: 3.23
*Average grade for 2 absences: 3.08
*Average grade for 3 absences: 2.68
*Average grade for 4 absences: 2.30
*Average grade for 5 or more absences: 2.01
*Average grade for 8 or more absences: 1.67
*Average grade for 12 or more absences: 1.25

Shocking, I know.
 
2) Students often think professors revel in student's poor performance; that we want to force rank students into something resembling a normal curve.  Here's the secret....we really don't.  I'd much rather see success on exams than failure.  As most managers know, giving quality feedback takes time.  It is much, much easier to grade an exam where a student gets an answer correct, than when he or she has made a number of mistakes.  A student's absence, more likely than not, means less success on an exam, and subsequently more work for me.

So, my attendance policy is a continual work in progress:

As attendance is significantly correlated to performance, there is an expectation you will be present for each class.  Unless your final grade is in the A range, the following penalties will be assessed (except under extreme circumstances):
1-4 absences – no penalty
5th absence – 2 points
6th absence – 4 points (for a total of 6 points lost)
7th absence – 8 points (for a total of 14 points lost)
8th absence – 16 points (for a total of 30 points lost)
9th absence – 32 points (for a total of 62 points lost)
10th absence – 64 points (for a total of 126 points lost)
11th absence – 128 points (for a total of 254 points lost)

If you are not present for 80% of the time class meets, it will be considered an absence.  I do not distinguish between “excused” or “unexcused” absences.  In essence, you have 4 absences to do with as you please.  However, if you burn them early, and a situation arises later that might cause you to miss class, do not expect a lot of sympathy from me.


I think that it provides significant flexibility (though students might think differently). Stuff happens during a semester - illness, job interviews, travel, car breaks down, a competing college-related event.  Four absences (essentially a week of classes) should be sufficient to meet most circumstances that a student might face over the course of a semester.  Similarly, the exponential penalties are significant enough to discourage more absences than that.

Yet, there are always new excuses and challenges that cause me to revise it yet again....but you'll have to wait until Monday to read about it.

So, have at it, people.  What flaws do you see?














Choosing a Pediatrician Should Be Like Choosing an Employee, Shouldn't It?

by Matthew Stollak on Thursday, February 21, 2013



So, my wife and I are expecting twins in the next couple of months.  Anxious times.

Of the hundreds of decisions that we are making, one is the choice of the pediatrician taking care of our children.  Choosing one shouldn't be any different than choosing an employee, right?  All, I assume, meet the basic qualifications of the position - knowledge, education, abilities, etc, or they wouldn't be already hired and hanging out their shingle.  So, it comes down to word-of-mouth referrals, and the interview.

We are going through a series of "meet and greets" to find the "right" one, much like a manager would interview a potential applicant.   We went through our first one yesterday.  Questions were posed, such as:

"How many years have you been at this clinic?"
"How many children have you served?"
"What's your perspective on medicating kids with behavioral problems?"
"Have you rejected any patients?"
"Have any patients rejected you?"
"At what age do you stop seeing the patient?"

For the most part, I tend to take a distant view of my health care employees.  They have the proper certification, education, knowledge, skills, and abilities, and are still employed.  In terms of cost, if they are in network, what's the difference?  One doctor is as good as the next.  So, the interview process really is a search for some piece of negative information that would turn us away.  For my wife, it does come down to "fit;" does the pediatrician make her feel "comfortable," and does he/she come across as a "know-it-all."

So, parents in the know....what am I missing?

God Made A #HR Professional

by Matthew Stollak on Sunday, February 3, 2013

There were lots of mediocre ads during the Super Bowl.

However, the ad of the night, for me, was the Dodge Ram Farmer ad, featuring some brilliant still photography, and the iconic voice of Paul Harvey.  Check it out below:

 

I anticipate that SHRM is rapidly working on a "So God Made A HR Professional" ad, perhaps in time for the Annual Conference in June.

So, if you were SHRM...

What should the ad say?

Who should do the voice over?
