Final answer:
The representation of 'Other' on a bar graph depends on the context, as it usually includes categories not covered by the main categories. 'Not enough information given to determine the answer' is often the correct response due to the dependency on context, such as the presence of overlapping categories or respondents who decline to provide information for specific categories.
Step-by-step explanation:
When evaluating the representation of "Other" on a bar graph in science, we find that "Other" often includes categories that are not covered by the main categories or those that do not fit neatly into a single category. In some cases, this may include participants who identify with multiple categories or choose not to disclose their information. Therefore, the option 'Not enough information given to determine the answer' is typically the most appropriate choice when considering whether "Other" should be represented on a bar graph. Context is key to making this determination.
For instance, if the bar graph is showing the ethnicity of students and there are students who do not identify with any listed ethnicities or have chosen not to respond to the ethnicity question, then it is essential to include an "Other/Unknown" category to account for these students. Omitting this category could lead to incomplete or misleading information, as displayed in Figure 1.10 with ethnicity categories and the Pareto chart.
Additionally, in situations where percentages add up to more than 100 percent because individuals can belong to more than one category, a bar graph is preferred over a pie chart. This is elucidated in the section on 'Percentages That Add to More (or Less) Than 100 Percent.' Pie charts require the total to be exactly 100 percent, whereas bar graphs can accommodate overlapping categories and cumulative percentages that exceed 100 percent.
