    Study Notes

    Types of Data Scales

    • Nominal Scale: Used for labeling variables without any quantitative value. Examples include gender, race, and hair color.
    • Ordinal Scale: Emphasizes the order of values but does not indicate the degree of difference between them. Examples include rankings like first, second, and third.
    • Discrete Data: Represents distinct or separate data that relies on counts. Examples include the number of students in a class or the number of cars in a parking lot.
    • Continuous Data: Represents an unbroken set of observations that can be measured on a scale. Examples include height, weight, and temperature.

    Types of Charts for Data Visualization

    • Bar Chart: Commonly used for visualizing comparisons of data across different categories. Effective for displaying data that can be categorized easily.
    • Column Chart: Best for comparing averages or percentages between 2 to 7 different groups. This chart uses vertical bars for presentation.
    • Histogram: Suitable for illustrating sample distributions on dimensions measured with discrete intervals. Shows frequency distribution of data points.
    • Line Chart: Best for illustrating trends over time. Ideal for time-series data to see changes at specific intervals.
    • Scatter Plot: Useful for examining the relationship or correlations between X and Y variables. Highlights patterns or clusters in data.
    • Pie Chart: Best used to illustrate the proportion within groups based on one variable. Best applied to categorical data that forms a whole.
    • Grouped Bar Chart: Best for comparing averages or percentages between 2 to 8 different groups with x-axis mainly for mutually exclusive categories.
    • Stacked Bar Chart: Ideal for illustrating the proportion within groups based on one variable. Should only be used with a group of categories that combine to make a whole.
    • Box Plot: Used to illustrate sample distributions on dimensions measured with discrete intervals. Highlights medians, quartiles, and outliers in data.
