    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.
