    Study Notes

    Network-Based Data Analysis

    • Uses low power
    • Requires good network connection
    • Can perform group-based analytics

    Advantages of Continuous Activity Monitoring

    • Daily observation of behavior
    • Long-term monitoring

    Types of Data Analysis

    • Qualitative
    • Quantitative

    Principles of Qualitative Analysis

    • Notice things
    • Think about things
    • Collect things

    Quantitative Analysis

    • Involves data dispersion
    • Involves contingence
    • Involves correlation

    Data Dispersion

    • Range
    • Average absolute deviation

    ANOVA

    • Normality: if the distribution of each group is normal

    Statistical Measures

    • Variance: the expectation of the squared deviation of a random variable from its mean

    Statistical Models

    • Complete
    • Incomplete

    Tables in Statistics

    • Contingency table (also known as cross tabulation)
    • Displays frequency distribution of variables
