Step-by-step solution

5 steps

To construct the bar graph, follow these steps:

  1. Title and Axes

    Give your graph a clear title, such as "HIV Positive Cases Detected in 2012 by Age Groups and Sex." Draw a horizontal X-axis and a vertical Y-axis. Label the X-axis "Age Group (years)" and the Y-axis "Number of Cases."

  2. Scale the Y-axis

    Examine the data to find the maximum number of cases in any single category (e.g., 415 for females in 20-24 years). Choose an appropriate scale for the Y-axis, ranging from 0 to at least 450 or 500, with regular intervals (e.g., every 50 or 100 units).

  3. Plot Age Groups on X-axis

    Divide the X-axis into sections for each age group: 0-4 yrs, 5-9 yrs, 10-14 yrs, 15-19 yrs, 20-24 yrs, 25-29 yrs, 30-34 yrs, 35-39 yrs, 40-44 yrs, 45-49 yrs, 50-54 yrs, 55-59 yrs, and 60 yrs above. Leave a small gap between each age group's set of bars.

  4. Draw Grouped Bars

    For each age group, draw three adjacent bars:

    • The first bar represents the number of Male cases (e.g., for 0-4 yrs, draw a bar up to 21). Color this bar Blue.
    • The second bar represents the number of Female cases (e.g., for 0-4 yrs, draw a bar up to 19). Color this bar Red.
    • The third bar represents the number of Gender not specified cases (e.g., for 0-4 yrs, draw a bar up to 1). Color this bar Green. Ensure the height of each bar corresponds to the number of cases on the Y-axis.
  5. Add a Legend

    Include a legend on your graph, as provided in the question, to indicate what each color represents:

    • Blue: Male
    • Red: Female
    • Green: Not specified gender
