2. • Data handling is the process of collecting, organizing and
presenting the data in such a way that is helpful to
analyse and make the conclusion.

Bar chart
Line chart
Pie chart
Histogram

4. • A pictograph is a way to represent data using images.
Each image in the pictograph represents a certain
number of things. In other words, a pictograph uses
pictures and symbols to convey information about the
provided data.

6. • A bar chart or bar graph is a chart or graph that
presents categorical data with rectangular bars with
heights or lengths proportional to the values that
they represent. The bars can be plotted vertically or
horizontally. A vertical bar chart is sometimes called a
column chart.

8. • The line chart is a simple, two-dimensional chart with
an X and Y axis, each point representing a single
value. The data points are joined by a line to depict a
trend, usually over time.

10. • Pie Chart is a circular representation of data. It is
called a pie chart because the sectors of the circles are
just like the slices of a pie. The area within each sector
(slice) represents the size of the data. The area of each
sector is directly proportional to the frequency of the data.

12. • A histogram is a graph used to represent the
frequency distribution of a few data points of one
variable. Histograms often classify data into various
“bins” or “range groups” and count how many data points
belong to each of those bins.
• A histogram has an appearance similar to a vertical bar
chart, but there are no gaps between the bars. Generally,
a histogram will have bars of equal width.
