Step 1
Draw an appropriate graph with axes labelled correctly
Answer
To accurately represent the data, a column graph is preferred. First, label the horizontal axis as 'Influenza season (Year)' and the vertical axis as 'VE (%)'. Make sure to scale the vertical axis appropriately, starting from 0 to 70, to accommodate the highest value, which is 60%.
The seasons to be represented are:
- 2006–2007
- 2008–2009
- 2010–2011
- 2012–2013
- 2014–2015
Step 2
Data plotted accurately
Answer
Plot the following data as columns:
- For the year 2006–2007, draw a column reaching up to 52%.
- For 2008–2009, plot a column reaching 41%.
- For 2010–2011, draw a column reaching 60%.
- For 2012–2013, represent with a column up to 49%.
- Finally, for 2014–2015, plot a column reaching only 19%.
Label each column with its respective VE value above the column.
