A

A research design that examines the extent to which two variables are associated.

  • A statistical association between variables
  • Scores are associated in a non-random fashion
  • Only measures things.

Q

Random Assignment

A

Participants in the experiment are randomly sorted into groups

23
Q

Experiment Group

A

The group of participants that receives the manipulation

24
Q

Control Group

A

The group of participants that does not receive the manipulation

25
Q

Between-Participants Design

A

A.K.A Between-Subjects

  • Researcher randomly assigns people to different groups
  • Each participants takes part in only one condition of the experiment

Random Assignment: Randomly assigned to different groups

26
Q

Within-Participants Design

A

A.K.A Within-Subjects

  • Each participant acts as their own control
  • Each participants engages in every condition of the experiment

Counterbalancing: Randomly assigned order of conditions.

27
Q

Confounding Variable

A

Any variable that differs between the different groups (conditions) of the experiment besides the manipulated variable.

28
Q

Placebo Effect

A

Improvement resulting from the mere expectation of improvement.

  • Countered with Blinded Experiments
29
Q

Blinded Experiments

A

Participants are unaware if they are in the experimental group or control group.

  • Used to counter the Placebo Effect
30
Q

Nocebo Effect

A

Harm resulting from the mere expectation of harm.

31
Q

Experimenter Expectancy Effects

A

Researcher’s hypotheses lead them to unintentionally bias the outcome of a study

  • Countered with Double Blind Experiments
32
Q

Demand Characteristics

A
  • Cues that participants pick up from a study that allow them to generate guesses regarding the researcher’s hypotheses
  • Can affect responses; Participants may behave the way they think they are expected to behave
  • Counteract with “cover” stories and distractor tasks
33
Q

Double Blind Experiments

A

When neither the researchers nor the participants are aware of who is the experimental or control group.

34
Q

Ethics

A

Represent a system of moral principles and standards.

35
Q

Research Ethics Board (REB)

A

An independent institutional committee that evaluates whether proposed research projects with human participants complies with the TCPS-2 principles and guidelines.

36
Q

Tri-Council Policy Statement (TCPS-2)

A

Mandate: “To promote research that is conducted according to the highest ethical standards.”

Core Principles:

  • Respect for Persons
  • Concern for Welfare
  • Justice
37
Q

Respect for Person

A

Respect autonomy & protect those with developing, impaired, or diminished autonomy.

38
Q

Concern for Welfare

A

Quality of life (financial, etc.); physical and mental health

39
Q

Justice

A

Fair and equitable treatment

40
Q

Informed Consent

A

Informing research participants of what is involved in a study before asking them to participate

  • The principle that people have the right to make a voluntary informed decision about whether to participate in a study.
41
Q

Deception

A

Researchers intentionally withhold information from (passive) or intentionally mislead (active) participants about the nature of the study.

42
Q

Debriefing

A

A conversation or communication with the participant that conveys additional information about the study.

  • Provide complete information about the purpose of the study
  • Give the participants a chance to ask questions
  • Minimize negative effects/feelings
43
Q

Animal Research as a Ethical Issue

A

Is the knowledge gained worth the suffering?

  • Animals give us important “models” to learn from
  • Some research may not generalize

Questions around the use of animals in research are complex, it is important to keep the context in mind

44
Q

Descriptive Statistics

A

Numerical characterization that describe data

45
Q

Inferential Statistics

A

Mathematical methods that allow us to determine whether we can generalize findings from our sample to the full population.

46
Q

Statistical Significance

A
  • Unlikely to be due to chance alone
  • Conventional threshold is 5/100 or p (probability) < 0.05
  • Does not equal practical significance as large samples can lead to statistically significant results
47
Q
A
48
Q

Central Tendency

A

Measures the “typical”/”central” scores in a data set.

e.g., Age in a university class: 18, 20, 22, 22, 23

49
Q

Mean

A

The average of the dataset

  • Advantage: Includes all numerical information in dataset
  • Disadvantage: Heavily influenced by outliers
50
Q

Median

A

The middle score in the data set.

51
Q

Mode

A

The more frequently occurring score in the dataset.

52
Q

Variability (Dispersion)

A

Measures of how scores vary

  • How loosely or tightly bunched the scores are
53
Q

Range

A

Difference between the highest and lowest scores
