WEEK 5: DEVELOPING HYPOTHESIS
1. · One way the field of science/psychology, they except something as being true - is a very critical
percentage: - 0.05 (5%)
2. In research, the is often used as a
threshold for accepting a hypothesis: less then 0.05 (5%) significance level
3. in quantitative research
Hypothesis:: a specific prediction about a new phenomenon that should be ob- served if a particular theory is accurate
4. · In quantitative research the hypothesis should be
because
: - framed positively
- its easier to prove something exists rather then to prove it does not exist
5. Hypothesis cycle: - Theory construction/revision
- Hypothesis Derivation
- Hypothesis testing Theory
Evaluation
6. Characteristics of a Good Hypothesis (SPOTS PCB): -States the direction
-Preregistered
-Operationalizes Variables
-testable/falsifiable
-Specifies Variable Roles
-Positive
-Control vs. Mediator
-Be logical
7. Characteristics of a Good Hypothesis
Must be testable and falsifiable: · Must be possible to measure and potentially disprove.
8. Characteristics of a Good Hypothesis
Must be logical, not just a random guess: · Based on existing knowledge, not a random guess.
9. Characteristics of a Good Hypothesis
Must be positive:: To confirm that an effect or difference exists.

preregistered:: Involves documenting the hypothesis, method, and analysis plan in advance to reduce bias.
11.Characteristics of a Good Hypothesis
tates the direction of the expected relationship between variables: o (Indi- cates the expected relationship between
variables) - (e.g., Independent Variable -> Dependent Variable)
12.Characteristics of a Good Hypothesis
perationalizes Variables:: · Clearly defines how variables will be measured and categorized.
taking an abstract construct like depression that cannot be directly observed and transforming it into something that can b
directly observed and measured
13.Characteristics of a Good Hypothesis
pecifies Variable Roles:: · Independent (predictor), Dependent (outcome), Me- diator (explains how/why), Moderator
(defines when/where/who), or Control (held constant).
14.Characteristics of a Good Hypothesis
Control vs. Mediator:: · When control is not possible, it can be analyzed as a mediator, answering how and why questio
Moderators answer who, where, and when.

ontrol vs. Mediator:
When we cannot control something we treat it as a : me-
diator
