background image P101 Lecture 5 Notes- Exam 1 Review                  1-24-17    2 short answer questions (3 given, 2 will appear) 
  (1) Outline the procedure used by Barak, Lipson, and Lerman (2006) in their descriptive study of 
computers in the classroom. 
o  Who were the participants and how they were chosen? 
  Computer science majors at MIT 
  Happened to be in a specific class 
o  What was their main conceptual variable?    How students used laptops in classroom (amount of time on different materials)  o  How did they operationally define that variable?    Naturalistic observation by walking around classroom putting tally marks for whether screen  was something class-related, class-unrelated, or neutral (closed/screensaver)  o  What were their results?    Students largely (83%) used laptops for class-related work  o  Explain how their study was limited in terms of:    Reactivity    Change in behavior when being watched 
  Could have switched screens when observers came near 
  External validity    How study applies to any group outside the one tested 
  Only observed computer science students (very specific group, had reason to have a 
computer)    Does not necessarily apply to other kinds of students; low external validity    Internal validity    How strongly causal statement can be made 
  Cannot be made here- did not manipulate anything, no grade observations made (no second 
variable)    (2) Be able to interpret means and standard deviations (see #6 on quiz 1) 
  (3) Be able to interpret something like Cora’s correlational study from quiz 1 and use information 
provided in scenario to draw scatterplot 
o  𝑥- and 𝑦-axes (time in shower, performance in class) 
o  If no units given, pick something; pick a range for each variable (for quizzes, out of 8 points) 
o  10 data points (10 quizzes in class) 
o  Know direction of correlation and what it means 
o  Title on graph 
o  Correlation ≠ causation 
  Things to Study (not comprehensive)  o  Material not covered in class is fair game, but focus on bolded words 
o  3 major approaches to research 
  Descriptive 
  Correlational 
  Experiments 
  For each one, consider: 
  Reactivity 
  Variables- conceptual (point to get across) and operational (how it is measured- be specific); 
in experiments, IV and DV    Internal validity- low if confounding variables present; experiments have the most 
  External validity 
  Research ethics
