### Ashton Markwart-Vinet's graph post

Ashton's graphing post !!!!!!!!!!!!!

There are five types of graphs, the five are bar graph, line graph, circle graph, double bar graph , and pictograph.

Bar graph :
Advantages: the advantage of using a bar graph is that you can compare many sets of data
Disadvantages: the disadvantage of using the bar graph is that you have to make the intervals equal

Circle graph:
the advantages of using the circle graph is that you can compare portions out of a whole.
Disadvantages: the disadvantages of using the circle graph is that you have to find th percentages of the portion and divide it to the whole

Line graph

Advantages: the advantages of using the line graph is that you can watch your trend increase or decrease.

Disadvantages: the disadvantages of using the line graph is that you can only compare rates of your own trends rather than multiple trends.

Double bar graph

Advantages: the advantages of using the double bar graph is that you can compare two sets of data across catagories.

Disadvantages: the disdvantages of using the double bar graph is depending on the data of your intervals it my not be even.

Pictograph

Disadvantages: the disadvantage of using a pictograph is that the numbers and the symbols are hard to work with.

2. How can graphs be misleading. Show 3 ways.

option number one distorting the size of the bar.

option number two making the bar 3-d

Option three change the colour of the bar

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

1.bar graph

2 line graph

2b) If you were selling pizza subs would you continue? How does your graph explain your awnser?

If I was selling pizza subs I would continue on selling pizza subs because the sales and the popularity of this produt keeps on rising as shown in the graph over a time period of 4 weeks as shown above in the two graph that I have made up above.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?
I would use the pictograph because it shows information by using pictures.

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.
In order to make my information look more impressive I would change the colour on the line graph, and for the pictograph I would change the size and colour for the pictures.
