    I am concerned about retention rate of a course. I have data of the 1st class compared to 2nd class for several semesters. I want to predict what will happen with retention if I add a 3rd class. Any suggestions?

    CollegeHelp:Are you the course coordinator?What is the historical retention for your first two classes. My retention in stats classes was 95% or higher compared to the historical departmental average of about 65%. One of my classes got bigger during the year. It was easy for me to see how to increase overall retention for statistics classes. It did not sit well with the other instructors.Adding the third class to the same course has so many factors influencing the retention it would be impossible to predict.Possible factors include:- New instructor vs. more load for existing instructors.- Evening slot vs. daytime slots.- Decreased class size for all three sections.- Standardizing course material and delivery with the added section.Most instructors know what are the most important factors governing retention.Cheers, BTDT

    Sorry I didn’t explain the data very well. I am a Dean that uses Six Sigma quite a bit for industrial training but I am trying to use with my processes. I have a Pharmaceutical class that starts in the fall and ends in spring. I have repeated this class since the year 2000. The VP’s at the college are encouraging us to remove a math component out of the class and make a third class. My hypothesis is that if I add more hours (by adding a third class) I will not be able to retain enough students for the additional class. From the Fall classes the mean is 34 students with a SD of 11.54 and the Spring Classes the mean is 14.1 with a SD of 4.012.

    CollegehelpIf the VPs are happy that the graduates will still be able to tell the difference in the half-life behavior of 2 tablets once per day and 1 tablet twice a day then OK.Let me see if I understand this. You have one single semester course that is offered twice per year. For discussion you have:Fall(Phar) 3 hours/week (mean 34 students, sd 11.54)Spring(Phar) 3 hours/week (mean 14.1 students, sd 4.012)So the students choose to take the course either in the fall or spring.You wish to change to:Fall(Phar-math) 3 hours/weekSpring(Phar-math) 3 hours/weekSummer(Phar-math) 3 hours/week…or when you say ‘remove a math component out of the class AND make a third course, do you mean ‘make a third course out of the math component’ so the new situation will be like the following?Fall(Phar-math) 2.5 hours/weekFall(Math) 1 hours/weekSpring(Phar-math) 2.5 hours/weekBTDT

    No, this course started in 1999 as one course, then it was split into two courses, Level 1 and Level 2. The VP’s are wanting to pull the math component out of the two levels and make a Level 3.
    This means the students will be going from 32 hours to 64 hours to possibly 84 hours total.

    Some basic questions to help in understanding the situation:  what are the VPs trying to achieve?  What has moved the VPs to make this decision?  What is their aim in wanting to make the split?  What positive outcomes are they trying to achieve? 
    Best of luck,
