             How to analyse data
           Make a tally table to show the data 
          gathered for each closed questions.
      i.e. Question 1 : Are you male or female?
                          Male                       Female

        Bar charts
   Use a bar chart to compare two or more values 
        with a small set of results.
 Drawing a bar chart
   In a bar chart, the height of the bar shows the 
         frequency of the result.
  As the height of bar represents frequency, label the 
 vertical axis 'Frequency'. The labelling of the horizontal 
  axis depends on what is being represented by the bar 
              chart.
       Line graphs
   A line graph is often used to show a trend over a 
  number of days or hours. It is plotted as a series of 
  points, which are then joined with straight lines. The 
  ends of the line graph do not have to join to the axes.
