What is Data Grouping of Grouping of Data?
The previous example can be solved by grouping data properly. It can be easier to count if these values were grouped with their type. Let’s do that for the previous example only,
We have the following data:
Camus, Kafka, Nietzsche, Camus, Camus, Nietzsche, Kafka, Camus, Camus, Kafka, Kafka, Kafka, Kafka, Camus, Camus, Nietzsche, Kafka, Camus, Kafka, Kafka
We see that there are three entities here: Camus, Kafka, and Nietzsche. Let’s count their occurrences and group them by their occurrences in a table.
The lines and crosses on them are called tally marks. They sometimes make it easier for us to count the number of objects. Now we can see that the least liked author is Nietzsche. The value in the “Number of Occurrences” column is called the frequency of that entity and this table is called frequency distribution.
Grouping of Data
Grouping of Data: Data Handling or Handling of data is not just a mathematical term but is used in everyday life. When there is a requirement to record, gather, and present any type of information or data, data handling is preferably used. Statistics is a word we often hear, is not but another term for data handling. From making a bar chart of favorite candies of different students to representing a large survey done on COVID-19 cases, data handling is used and preferred.
This information in such cases is called Data. Data can be represented in both statistical ways and graphical ways. Graphical ways usually visually appealing are also easier to understand by a common person. There are many ways to represent data graphically:
- Pictograph
- Bar Graph
- Double Bar Graph
