SOCR Surveys - Student Survey Results -- Fall 2005 Stat 100A (Sanchez)

Summary of Results (red=proportion of SOCR group students that answered that out of total 19 responses); blue=proportion of control (39 responses). Numbers over a category may not add up to 100% due to some nonresponse to a given question.

Note: Because of the confidential nature of this survey, we could not separate the biostatistics and other graduate from the undergraduate students and therefore, the opinions of the treatment group are not those of the smaller group represented in the table of quantitative outcomes.

Please, complete parts I and II of this survey

Part I

Compared with other classes where instructors have not required using technological tools like applets or software for some homework,  how would you rate the overall effectiveness of the use of the technology  (check what applies)

Please, check what applies in questions 1-3 and  answer questions  4-6:

1.- Was this  class     62% 73% more interesting or    24%  21% less interesting than other applied math classes that you have taken?

2.- Was this  class      27% 42% harder  or       54%  42% easier  than other  applied mathematics classes that you have taken?

3.- Did this Probability class teach you      62% 84% more  or     27%  10% less  things relevant to your  own life than other applied mathematics classes ?

4.- Has this  class helped you understand better the world around us?   Circle one

                             70%  63% YES                                    24%    26%  NO

If you answered YES, write below in what way the class did so

  • Poisson, normal, exponential distributions are common in our world.
  • Now know to make decisions based on probability
  • The examples gave us some ideas about how stats can be used in the real world
  • Some practical questions are really interesting. I like the examples involving probability in marketing, diseases
  • Learned a new software
  • The type of situations you can use probability to understand events
  • It make me think about decision making from a different viewpoint
  • It made me more aware
  • Gave lots of examples that were related to our life
  • Using events from actual society
  • Helps me figure out complex phenomena by using probability easily.
  • I learned to compute the probability (chances) of life events
  • When I study econ it helps me
  • There were a lot of real life examples
  • Got to know probability
  • Probability as applied to life
  • Helpful to get into Stat field
  • Clarified many things I did not notice or did not understand before
  • Because this is the first applicable class to the real world it helps me understand business decisions
  • Clearer understanding of Statistics
  • Deepened my understanding of statistics as chance

  • In understanding how probability works for real life examples
  • Understand the uncertainty in real life, which is very interesting
  • It explain some things that happen in life. Made me understand better
  • Slightly changes the way I consider my options, and therefore the nature of my decision making processes
  • It helps me when I play games understand my chances of winning, losing, my chances of getting the job
  • Everything has a chance of happening or not happening, or even in a different way.
  • There were many examples in this class, which demonstrated the application of statistics to real life
  • Through applications of class materials
  • Through understanding probability theory
  • It allows me to understand the patterns and principles of events

If you answered NO, has the class made it harder for you to understand the world or has it not changed your understanding of the world?

4 responses, saying that it has not changed understanding

4 responses, saying that it has not changed understanding

5.- Would you take another applied probability class after this one if you had a chance (meaning a class where you would do more real world applications of probability to acquiring knowledge in different contexts such as industry, weather, government decision-making, etc)?  Circle one.

81%   78% YES                             19% 15%   NO

6.- What in the material of this  course do you consider to be the piece of knowledge that will help you the most in your life? Please write your answer below.

  • Integrals
  • Most of it
  • Knowing frequency of poker hands
  • Probability theory underlying statistics
