The types of graphs we learned was...
- Line graphs
Disadvantage: The disadvantages of a line graph is that depending on the intervals the data will be harder to identify and you will not exactly know where the dot is unless it is exactly on the next line.
- Bar Graph
Disadvantages: The disadvantages of a bar graph is that it is pretty much the same concept as a line graph, the intervals can not be that accurate to identify and hard to see exactly where the bar is at.
- Double Bar Graph
Disadvantages: The disadvantages of a double bar graph is that the intervals can be hard to find out exactly where the dot or bar is.
- Circle Graph
Disadvantages: The disadvantages of a circle graph is that if the percentages are really close it is hard to tell what is bigger or if it is the same, another disadvantage is that if the percentage is not printed or placed under a category it is hard to name exactly what the actual percentage is.
- Picto Graph
Disadvantages: The disadvantages of a pictograph is that it is hard to see if a symbol is cut in half or 1/3 etc.
- Double Line Graph
Disadvantages: The disadvantages of a double bar graph is pretty much the same as the double bar graph, it is hard to exactly pin point where the bar or the dot is specifically because the intervals cannot be that accurate.
2. How can graphs be misleading? Show 3 ways.
Graphs can be misleading if......
- You make one of your graphs wider or 3D so it might make people think that its doubled of some sort and to show that it is popular.
- You make your pictures in a picto graph different sizes to show that you can show if you really like it or if it is important of some kind.
- You add the break in the y-axis to make the lowest amount of data seem smaller than usual and make the higher pieces of data seem larger than usual.
