Data Handling

Data
Data is a collection of numbers gathered to get some information.

To get the required information, all observations should be recorded.
Tally marks are used to organise the observations. Record every observation by a vertical mark, but every fifth observation should be recorded by a mark across the four earlier marks, like this:.  We depict each observation with the help of tally marks.

For example,  a group of persons and their sizes of shoes. The tabular form representing the tally marks is as shown here.
