    Question

    Which type of data visualization is most useful for

    identifying the relationship between two continuous variables?
    A Histogram Correct Answer Incorrect Answer
    B Box plot Correct Answer Incorrect Answer
    C Scatter plot Correct Answer Incorrect Answer
    D Pie chart Correct Answer Incorrect Answer
    E Bar chart Correct Answer Incorrect Answer

    Solution

    A scatter plot is the most effective visualization for examining the relationship between two continuous variables, as it displays individual data points on a two-dimensional plane. This allows analysts to observe trends, correlations, and potential outliers directly. By plotting one variable on the x-axis and the other on the y-axis, scatter plots reveal patterns that can indicate the strength and direction of a relationship, such as positive, negative, or no correlation, thus providing valuable insights for further statistical analysis. The other options are incorrect because: • Option 1 (histogram) shows data distribution for a single variable, not relationships. • Option 2 (box plot) is useful for displaying variability but not for showing relationships between variables. • Option 4 (pie chart) represents categorical data proportions and does not support continuous variable relationships. • Option 5 (bar chart) compares categories rather than continuous relationships.
