Final answer:
A subdivided bar graph is an effective way to display numerical order and distribution of players' birth years by decade, as it combines the clarity of a bar graph with the detailed comparison of a pie chart.
Step-by-step explanation:
To display the data of players' birth years in a way that best shows the numerical order and the distribution of data by decade, a bar graph is a suitable choice. This type of graph clearly demonstrates how the data is distributed over time, and it allows for easy comparison across different time periods or categories.
Based on the provided examples, a subdivided bar graph can effectively show the distribution of players' birth years by decade. In this context, each bar would represent a decade and within each bar, subdivisions could indicate the count or percentage of players born in each year of the decade.
A subdivided bar graph combines the clarity of a bar graph with the detail you might find in a pie chart. As shown in Figure A8(c), this can also be done using percentages to represent parts of each bar, if we want to focus on the proportion of players born in each year relative to all players born in that decade.
