Study Notes

Recap: Data Collection and Levels of Measurement

Data collection is an important step in research.
There are four levels of measurement for data: nominal, ordinal, interval, and ratio.
Nominal scales describe categories and are often used for classifying data.
Ordinal scales allow data to be ranked in order, but intervals are unknown.
Interval scales are based on scales where the distance between them is equal and meaningful.
Ratio scales are the most meaningful, having an absolute true zero point.

Data Analysis - Quantitative

Quantitative data analysis involves analyzing numbers or figures.
There are two broad types of quantitative data analysis: descriptive and inferential.
Descriptive statistics describe or summarise sample data.
Inferential statistics attempt to generalize findings from a sample to a wider population.

Data Analysis - Qualitative

Definition: The process of making meaning from non-numerical data.
Forms: Interview transcripts, documents, open-ended survey responses, images and videos.
Purpose: To understand people and situations by analyzing meaning and context.

Qualitative Data Analysis Methods

Qualitative Content Analysis: Systematic analysis of the content of textual materials to identify patterns, themes, and relationships.
Narrative Analysis: Treats the transcript as a story, following a specific sequence and answering the question "And then what happened?"
Discourse Analysis: Focuses on written or spoken language, analyzing how it is used in a social context.
Thematic Analysis: Identifies common themes and patterns from transcribed interviews and focus groups.
Grounded Theory: A systematic approach to developing a theory from qualitative data.
Interpretive Phenomenological Analysis (IPA): Aims to understand people's unique experiences of a phenomenon.

Transcription of Data

Interviews and focus groups are typically recorded and then transcribed.
The transcription process involves writing a verbatim record of the recordings, including pauses, hesitations, laughs, etc.

Verification of Qualitative Data

Verification ensures the reliability and validity of qualitative research.
Several methods are used to verify qualitative data, including triangulation, reflective journals, data saturation, and member checking.
Triangulation: Involves using multiple sources of data to check for consistency.
Reflective Journal: A diary kept by the researcher to document personal thoughts, biases, and experiences.
Data Saturation: Indicates that the researcher has collected enough data to support the study.
Member Checking: Involves taking the data back to participants for feedback and confirmation.
Self-Disclosure (Reflexivity): The researcher reflects on their own potential biases and how they might influence data.
Meticulous Record-Keeping: Ensures transparency and consistency by documenting the decision-making process.

Homework Exercise

Identify the six most popular qualitative data analysis methods: Qualitative content analysis, Narrative analysis, Discourse analysis, Thematic analysis, Grounded theory, Interpretive phenomenological analysis.
Explain the concept of social constructionism: The idea that social phenomena are not objective realities, but rather products of social interaction and shared understanding within a culture.
Why is gender a social construct? Gender roles and expectations are socially created and vary across cultures and time periods.
What is triangulation? A data verification method that involves using multiple sources of data to check for consistency.
Why is data verification important in qualitative research? To ensure the reliability, validity, and trustworthiness of the findings.

Homework Exercise: Part 2

Which method of analysis would be most suited to understanding the personal experiences of young adults raised by a parent with a mental health problem? Interpretive Phenomenological Analysis (IPA) would be most suitable for exploring their unique experiences and perspectives.
What is the relationship between the number of hashtags and likes on TikTok? Researchers found that a higher number of hashtags was related to more likes.
