These are the types of graphs you will need to learn:
Picture graph Column or bar graph Line graph Pie or sector graph Divided bar graph Travel graph
Picture graphs tend to be used in magazines or newspapers often for “less serious” data For example, in the Easter Eggs picture graph above, Lauren found the 30 eggs which was the least number out of the four people in the egg hunt
A column graph has spaces between the columns and can be single or double. All columns should be the same width. For example, in this favourite sport column graph we can see that twice as many girls like soccer compared to the number of boys who like soccer.
A line graph is particularly useful for continuous data because it joins the data points and shows the trend over time. For example we can see above that the general trend of the day was for the temperature to increase until 2pm and then decrease
Whilst the dotted lines are still shown on the chart above they are really just guidelines that help you construct the chart. A key at the side should also be used if you cannot write on each piece.
A divided bar graph can have a key or scale. If you are constructing one yourself it makes it easier if you make the length a distance that can be divided easily (eg 10cm, 20cm)
Now it’s time for you to practise drawing and reading these different types of graphs. Remember it is important to pause and think about why each graph is used in each case because each type has different benefits.
