Experiments

    Well you can tell by the way I design my experiment
    I use my mind
    Treatment A and Treatment B of the experiment is what you’ll see
    Because subjects-- they go in my big bag I shake them well
    Subjects-- they go in my big bag I shake them well

    When you need to spread unknown traits evenly - Randomize, RANDOMIZE
    When you need to spread unknown traits evenly - Randomize, RANDOMIZE
    RANDOMIZE to REDUCE BIAS, REDUCE BIAS
    RANDOMIZE to REDUCE BIAS

    Make an experiment what do you do?
    Control, randomize, repeat

    Make an experiment what do you do?
    Control, randomize, repeat

    Make an experiment what do you do?
    Control, randomize, repeat

     

    Make an experiment what do you do?
    Control, randomize, repeat

     

    Randomly assign to the treatment groups
    So you can claim the cause and effect

    I see you have a trait there
    That may affect the way subjects respond
    I see you have a trait there
    That may affect the way subjects respond
    What do you do
    Make homogeneous groups
    What do you do
    Make homogeneous groups

    Blocking reduces variation
    Blocking reduces variations
    Within each block is experimentation
    Within each block is experimentation

  • Shapesplosion is an on-line game in which a person is expected to place specifically shaped pegs into the appropriate holes within a short time period. In this project, students are asked to use the Shapesplosion game to design an experiment and collect data. This game is specifically designed so that students have the opportunity to develop and test their own unique research question. You can leave all the variables blank when you are simply trying out the game, however, if you want to find your score is the database of results, you will need to select the Participant Info box.

  • Memorathon is an on-line game in which a person is expected to repeat a sequence of buttons provided by an electronic device. Each time you successfully repeat the given sequence of buttons, the sequence gets longer. The challenge is to remember as long a sequence as possible. Cognitive psychologists test short-term memory using serial recall, which evaluates the ability of people to recall information in the specified order in which it was presented. Measuring how many items a subject can remember in order without an error, called memory span, is also studied. The Memorathon Game is an example of serial recall and memory span.  This on-line game provides students the opportunity to design multiple versions of the Memorathon Game in order to test which variables have the largest effect on memory. You can leave all the variables blank when you are simply trying out the game, however, if you want to find your score in the database of results, input any specific course ID and student ID.

  • Statistically Grounded is an on-line game that introduces multivariate issues in a simplified game environment. Students are asked to serve as a consultant for their friend, Joe. Joe is starting his own coffee company and students help him design a study to determine whether factors, such as location, time of day, price, type of music, or some combination of these influence sales. The on-line game allows students to design a study, sample data, and make suggestions on how Joe's business should be run. The game then simulates several months of business based on student's suggestions. The goal is to design a plan that will earn the most sales and make the largest amount of profits.
