Graphs

take the values from the chart

and then add all the observations by total number of observation!

it is good that it is not a polygon!

the points on a bar graph are not connected to each other.

A graph that displays data by using points joined together by line segments.

Figure out the percentage that 90 degrees is of a whole circle, which is 360 degrees. 90 / 360 = 0.25, or 25%. 25% of 600 is 150 people who went abroad.

You have two sides to a bar graph. Each side will have data. Let's say you are graphing a race. On the horizontal axis you could put the names of the racers and on the vertical axis you put the miles. You would then graph the number of miles for each racer in a bar form and color the bars in to show a comparison.

when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.

You can do it in several ways. One is to pick your colors so that you emphasize certain parts of the pie. Brighter colors or ones that are darker than the neighbor colors stand out more. This can make the reader emphasize certain parts of the chart when they otherwise would not. Next, pie charts are often presented in 3 d relief. If you point the top of the chart away from the reader you can distort the perception.

if you go on to bbc maths revition and type in on search pi with no e it should come up. :)

Line graphs are better for representing things that vary continuously, like temperature against time. Bar graphs are better for representing things that are counts not mapped against a continuous variable such as time, so in your case I would recommend a bar graph.

Histogram is a special type of bar chart. The use of a histogram is to present frequency counts or relative frequencies of the data. Histograms should be used when the frequency of occurrence is important. Perhaps I want to show the frequency of accidents based on the time they occurred. A histogram would have intervals of time. Bar charts are very useful for comparision purposes. Different color or shadings bars can allow for multiple comparisons. Bar charts are also used when the x-axis is not a numerical value, but a general category. In this case, the categories may be ordered, depending on their associated value. For example, you want to show which make of cars have the highest re-sale value, so you rank them from lowest to highest.

no

You would use a broken bar graph, when grouping and gathering information. You would use straight, slanted, or vertical lines and showing points with dots. A broken bar graph is just like a line graph.

The break allows the rest of a rising graph to be drawn lower on the paper or screen, instead of going right off the top.

the histogram has spaces in between each bar whereas the bar graph doesn't have spaces

work like diagrams
