Data:-
Data is the collection, classification and interpretation of required information or facts. It may be a collection of numbers, figures, words or symbols. There are two types of data- Primary Data and Secondary Data.
Primary Data is the data collected directly from the source.
Secondary Data is the data collected from secondary sources such as the internet, television and newspaper.
Tally Marks:-
Tally marks are a quick way of keeping track of numbers in groups of five.
One vertical line is made for each of the first four numbers, the fifth number is represented by a diagonal line across the precious four. The frequency of a given observation is the numbers of times it occurs.
Data Representation:-
Data is ordered and represented in many ways. Data Representation refers to the form in which data is stored, processed and transmitted.
