Study Notes
Measures of Central Tendency
- Mean is obtained by calculating the sum of values and dividing by the number of values in the data set.
- Median is obtained by finding the middle score when all scores are organized in numerical order.
Data Analysis
- Content analysis is used to analyze documented information in the form of texts, media, or physical items characteristics.
- Thematic analysis focuses on using stories and experiences shared by people to answer research questions.
- Narrative analysis involves looking at each case narratives.
- Grounded theory is used in conjunction with other methods.
Data Gathering
- Interview is a conversation where questions are asked and answers are given.
- Observation involves watching behavior, events, or noting physical characteristics in their natural setting.
- Questionnaire is a self-directing instrument structured with questions and indicators.
- Data gathering on qualitative search involves abounding with words and visuals.
Data Quality
- Best practices to ensure high-quality data include:
- Recording all relevant information as and when obtained.
- Double-checking manual data entry for errors.
- Assessing reliability and validity to get an indication of data quality.
- Performing transcriptions or data entry in systematic ways to minimize distortion.
Sampling Techniques
- Random Sampling uses randomization to make sure every element of the population gets an equal chance to be part of the selected sample.
- Systematic Sampling is used when every 'nth' element is selected from the population.
Research Paper
- The Data Collection Procedure helps readers understand how to collect and analyze data.
- Research Instruments are tools used to collect, measure, and analyze data related to research interests.
Research Ethics
- A Consent Form is an agreement between the researcher and the research participant outlining roles and responsibilities.
Research Measurement
- Reliability refers to the extent to which a research instrument consistently has the same results if used in the same situation on repeated occasions.
