Presentation of Data Test - 1

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

Salutation is not a part of table. It is a part of latter. For example  Dear Sir, Respected Madam,  etc.

These three can be prepared when data is given in the form of class intervals and corresponding frequencies.

An arithmetic line graph is also called time series graph. In this graph time (hour, day/date, week, month, year, etc.) is plotted along x-axis and the value of the variable (time series data) along y-axis.

A diagram in which the size of only one dimension i.e. length is fixed in proportion to the value of the data is called one dimensional diagram. Such diagrams are also popularly called bar diagrams.

Multiple bar diagrams are prepared by drawing two or more single bars corresponding to each year.

An area chart or area graph  displays graphically quantitative data. It is based on the line chart . The area between axis and line are commonly emphasized with colors, textures and hatchings. Commonly one compares with an area chart two or more quantities.

Legend is a picture or symbol or colour given to each graph to differentiate the bars with each other.

For "less than" ogive the cumulative frequencies are plotted against the respective upper limits of the class intervals

Frequently distribution can be framed from histogram. Frequently polygon and frequency curve can be prepared by converting the mid points of histogram.
