Question
20. The Bar graph is used in presenting the change or trend of a certain variable
*TRUE
False
Solution
Analysis of the Statement
-
Understanding a Bar Graph: A bar graph is a visual representation of data where individual bars represent different categories or groups. The height or length of each bar correlates to the value or frequency of that category.
-
Purpose of a Bar Graph: Bar graphs are primarily used to show comparisons between different groups or to display categorical data. They can effectively illustrate the differences in values among various categories, but they are not typically the best choice for demonstrating trends over time.
-
Trend Representation: To show trends or changes over time, line graphs are usually more appropriate, as they connect data points, making the trends clearer.
Conclusion
Given that a bar graph is not specifically designed to showcase trends or changes over time, the statement "The Bar graph is used in presenting the change or trend of a certain variable" is FALSE.
Final Answer
FALSE
