what advantages does bar graph have over pictograph explain with example
Answers
Answer:
When you are choosing to display data with graphs, does it matter which graph you choose? It does! That's because each different types of graphs have pros and cons when you use them. In order to most clearly demonstrate your data and your findings, you will have to learn how to choose the right graph.
When you've got data that has different categories, a bar graph is excellent for displaying your info. You're able to easily compare several data sets and it's visually straightforward when someone reads it.
However, an issue with a bar graph is that it can only be used with discrete data (data that only takes on certain values). It can also be misleading, since if you organize a bar graph a certain way, it could emphasize a certain effect even though that effect isn't actually that statistically relevant.
Other than a standard bar graph, there's something called the double bar graph. Double bar graphs allow you to compare two sets of data across categories. You're able to make comparisons across intervals (similar to a regular bar graph). Of course, there are also disadvantages to bar graphs. One of the main issues is that it's hard to determine fractions or find percents in your data when you've laid everything out in double bar graphs.
Pictographs are visually appealing graphs that are best used with data that can be represented with symbols. It's quite easy to read and can handle a large set of data well.
However, pictographs run into a problem when you're trying to show partial icons. It's a very simplistic type of graph, so you will not be able to show more complex observations in data sets with them. Lastly, it really only works well with 2-6 categories.
Answer:
Bar graphs use bars and numbers to show information, and pictographs use pictures to show information. With a pictograph you need to count each time to find how many, but with a bar graph you can just look at the number.
