Week 9
CONVERTING NOTIONS TO NUMBERS
Converting psychological notions
One of the most critical tasks in conducting research
i.e., defining an appropriate scale of measurement
Talked previously about different scales (nominal, ordinal, interval, ration)
Week 8
Non-Experimental Research
Case Study
Case studies make careful analysis of the experiences of a single individual or group
Most useful when phenomena being studied is extremely rare, or for when cases are extreme examples of the
phenomenon
Case st

Experiments
Chapter 7
Condition of a True experiment
Manipulate the independent variable
Systematically vary the level of the IV
Participants are assessed at different levels of IV
Randomly allocate participants to levels of IV
Each participant
Week 7
Research Design
Research Design
Two basic kinds of designs
1. One-way design = single independent variable
2. Factorial design = two or more independent variables
The simplest possible kind of true experiment is: a two-groups design
Two basic appro

DATA, VARIABLES & STATISTICS
(From Week 10)
Conditional Distributions
A conditional distribution shows the distribution of one variable for just the individuals who
satisfy some condition on another variable.
The following is the conditional dis
Week 3 & 4
Validity, Reliability and Measurements / Treats to Validity
Chapter 3 & 5
IV = the casual variable
DV = the outcome variable (changes in the DV are dependent upon variations in the IV)
Forms of Validity
Validity = The relative accuracy or corre
Week 10
DATA, VARIABLES & STATISTICS
Understand how to classify data
o 5 Ws of data
o Quantitative (continuous) and qualitative (categorical) data
Be familiar with rules for graphically representing data (single variable)
What are data?
Data can be numbe
Week 6
Quasi-experimental Research Designs
Understand the difference between true and Quasi- experiments
Know the different types of Quasi-experiments
Understand the strengths and limitations of quasi versus true experiments
True Experiments

How Do We Know?
Metaphysical Systems
Metaphysical: explanations that violate what scientists now consider to be established physical
laws, primarily by attributing behaviour or experiences to no physical forces such as spirits or
deities
