    Study Notes

    Types of Surveys

    • Panel Study: Tracks the same individuals over time within the same generational group.

    Sampling Bias

    • Sampling Bias: Occurs when the sample does not accurately reflect the population due to flaws in the sampling process.

    Reducing Bias in Surveys

    • Reducing Demand Bias: Strategies such as using blind studies, disguising the purpose of the study, and ensuring the respondents are not aware of hypotheses, can help minimize demand bias.

    Bias in Surveys

    • Non-response Bias: Likely to occur when participants are not motivated to take the survey, resulting in a biased sample.

    Experimental Manipulation

    • Experimental Manipulation: Aims to isolate the effect of a specific variable by systematically altering it.

    Within-Subject Experimental Design

    • Within-Subject Experimental Design: Compares different conditions or treatments within the same group of participants, allowing for more precise comparisons.

    Control Variables

    • Control Variables: Factors that are held constant during an experiment to minimize their potential influence on the outcome.

    Secondary Data

    • Secondary Data: Data that has been collected for a different purpose than the current study, and therefore not collected by the researcher to answer a specific question.

    Advantages of Quantitative Research

    • Generalizability: Quantitative research often focuses on larger samples, enhancing the generalizability of findings to broader populations.
