COMPONENT 2
DATA ANALYSIS
Data is information (facts and figures) that have been collated in a way that allows
them to be used to inform decision making.
A pie chart is a circular chart that is split into sectors to show
percentages or the relative value of different categories of data.

representation of the relative information

decisions

relationships like the impact of

in pie charts.
Data is grouped into categories using rectangular bars, with the
height of the bar representing the frequency for the category.
These bars can be presented vertically or horizontally. One axis
will show the categories being compared and the other axis will
show the frequency.

Histograms show quantitative data, and the data in a histogram is
continuous so there are no gaps between the bars which represent
the different intervals. The area of each bar is proportional to the
frequency for each interval. Both the x-axis and y-axis have a scale.

Line graphs are used to compare two variables. The x-axis
represents a continuous variable (e.g. time) and the y-axis
represents the second variable (e.g. quantity or value). A line graph
is plotted as a series of points and then joined to produce a
continuous line. The line graph shows the relationship between the
two variables.
