Study Notes

Aims

An aim can express the intention to investigate a link or relationship between two variables.
This type of study is referred to as a correlation.

Research Process

The research process includes:
- Development of an aim
- Selection of a research method and its designs, formats, or techniques
- Definition, manipulation, measurement, and control of variables and variables in hypotheses
- Participant selection
- Ethical considerations
- Data analysis, including drawing conclusions
- Research evaluation

Experiments

An experiment looks for a cause-and-effect relationship.
The independent variable (IV) is manipulated to see its effect on the dependent variable (DV).
The IV is manipulated to create 'levels' or conditions, e.g., bright or dull lighting, or early vs. late in the day.
The effect of these conditions on the DV is measured.

Self-Reports

Self-reports collect information directly from participants.
Two main methods of self-reports are questionnaires and interviews.

Questionnaires

Questionnaires present questions to the participant in written form, either on paper or online.
Questionnaires can use closed or open questions.
- Closed questions: Fixed set of responses, e.g., yes/no, multiple choice, rating scales (e.g., 0-5), Likert scales (strongly agree to strongly disagree).
- Open questions: Ask for descriptive answers in the participant's own words, typically "Why...?" or "Describe...".

Interviews

Interviews involve the researcher having a direct conversation with the participant, typically face-to-face or over the phone.
Interviews can use structured, unstructured, or semi-structured formats.
- Structured interview: Same questions in the same order for every participant, standardized procedure.
- Unstructured interview: Questions vary based on the participant's responses, flexible but difficult to compare data.
- Semi-structured interview: Combines fixed questions with participant-specific questions for flexibility and comparison.

Case Studies

A case study is a detailed investigation of a single instance, often a person, family, or institution.
Collects in-depth data using various techniques, like interviews, observations, tests, and questionnaires.
Useful for studying rare cases and tracking developmental changes.

Observations

Observations involve watching participants, either humans or animals.
In experiments, they can establish a causal relationship between the IV and DV.

Correlations

Correlations investigate the relationship between two variables, called co-variables.
It's important to note that correlations do not establish causality, meaning it is impossible to be certain that one variable causes changes in the other.
The relationship between co-variables can be described as positive or negative.
- Positive correlation: Higher scores on one variable are associated with higher scores on the other.
- Negative correlation: Higher scores on one variable are associated with lower scores on the other.

Quasi-Experimental Designs

These designs involve repeated measurements at different time points.
Useful for tracking long-term changes, especially after interventions like educational or health programs.

Variables

Variables are factors that change or can be changed.
In experiments, there are independent, dependent, and controlled variables.
In correlations, there are two measured variables called co-variables.
Operational definitions are important for clarifying the intended differences represented by the variables.

Manipulation, Measurement, and Control of Variables

In experiments, the IV is manipulated to create different conditions.
The DV is measured effectively to assess the effect of the IV.
It's important to control other variables that could influence the DV, ensuring the observed changes are due to the IV manipulation.
