Presentation of Data Test - 2

Caption is one of the part of a table.  It is not a form of presentation of data.

Ambiguous title may lead to wrong understanding or different understanding of title by the users.

Mean and mode can not be calculated by using graphical method.  Only median can be ascertained by constructing ogives.

Presentation of data involves presenting raw facts and figures in the form of tables, charts and diagrams which is easy to understand for the users of data.

By using cumulative frequencies,  we can prepare less than type and more than type ogive.

A shape with only two dimensions (such as width and height) and no thickness are called two dimensional diagrams.Squares, Circles, Triangles, etc are two dimensional objects.

The frequency curve is obtained by drawing a smooth freehand curve passing through the points of the frequency polygon as closely as possible. It may not necessarily pass through all the points of the frequency polygon but it passes through them as closely as possible.

Pie diagrams can be prepared by converting frequencies into angles in such a way that total of all angles should come equal to 360

Normal base line starts with zero,  if the data is far away from zero, it becomes very difficult to present the data in a graph which is far away from the point of origin,  therefore, a false base line is prepared.

Component bar diagrams are suitable for data having different components.  Similarly, Circles also can be used to present component data by sub dividing the circle and preparing pie chart.
