Bar graphs are effective for comparing discrete categories, making it easy to visualize differences in size or frequency. However, they can become cluttered with too many categories, which might confuse the viewer. Pie graphs excel at showing proportions within a whole, providing a clear view of relative sizes. Nevertheless, they can be misleading if there are too many slices or if the differences between them are subtle, making it hard to interpret accurate values.
A bar graph's strengths include its ability to clearly display comparisons between different categories and to handle a wide range of data types, making trends easily identifiable. However, its weaknesses lie in potential over-simplification, which can obscure nuanced differences, and it can be less effective for showing changes over time compared to line graphs. Additionally, if categories are not well-defined or if there are too many bars, it may lead to confusion or misinterpretation.
Pie graphs are good for showing a percent of something.
Yes.
data of what u want
pie graphs show volume and are good for showing the relationship of size. line graphs are good for showing trends which can lead to predictions.
Bar graphs, pie charts, and even line graphs can all be used to compare. I personally like to use Bar graphs when showing numbers.
Yes.
They are a useful device for showing parts or shares of totals.
the rate increase as you do more work
Learning to think critically about what graphs show us
It is great for showing a unit over time. This is usually a profit from a product.
