Statistics

Points to be Remember:-

1. Pictorial representation of the numerical data using picture

     symbols is called pictograph of the data.

2. A bar graph is a pictorial representation of the numerical data by a

    number of bars of uniform  width, erected horizontally or vertically,

    with equal spacing between them.

3. The uniform width of the bars and the uniform gap between them is

    suitably chosen, keeping in view the given information (data) and

    the space available for the diagram.

4. it is not necessary to make the bar graph on a graph paper, but

    from the point of view of convenience and accuracy, one should do

    so.

5. A bar graph should have a little. The chosen scale should also be

    mentioned below the graph.
