a pictogram is a bad choice for a graphical display because it may not accurately represent numerical data or convey precise information. Pictograms are visual symbols that use pictures or icons to represent data or concepts. While they can be effective for conveying simple and qualitative information, they are not suitable for displaying complex or precise numerical data, especially if accuracy and precision are essential.
Here are some reasons why pictograms may not be a good choice for graphical displays:
1. Lack of accuracy: Pictograms often represent data using pictures or icons that do not have a standardized or consistent meaning. This can introduce ambiguity and make it difficult to accurately interpret the information being displayed.
2. Inability to convey precise numerical values: Pictograms are primarily designed to represent qualitative or categorical data, such as different categories or types. They cannot accurately represent or convey precise numerical values, making them unsuitable for displaying data that requires exact measurement or comparison.
3. Limited scalability: Pictograms often rely on the size or arrangement of the icons to represent data. This can make it challenging to accurately compare or interpret data when the quantity being represented becomes too large or when the display needs to be scaled.
4. Potential for misinterpretation: Pictograms rely heavily on visual interpretation, which can vary from person to person. This can lead to misinterpretation and confusion, especially when the meaning of the pictogram is not obvious or well-known.
5. Inability to show complex relationships: Pictograms are generally simple and limited in their ability to represent complex relationships or patterns in data. They may not be able to capture the intricacies of data analysis or display trends, correlations, or patterns effectively.
In summary, while pictograms can be visually appealing and useful for representing qualitative or categorical information, they are not suitable for displaying complex numerical data or conveying precise information accurately. Other graphical displays such as bar graphs, line graphs, or scatter plots are better choices when it comes to representing and analyzing numerical data.
