Double- Bar Graph
Double-bar graphs are used when two groups of data are required to be represented on a single graph. In a double-bar graph, to represent two groups of data, they are represented beside each other at different heights depending upon their values.
Advantages of double-bar graph:
- A double-bar graph is helpful when multiple data are required to be represented.
- It helps in summarizing large and big data in an easy and visual form.
- It shows and covers all different frequency distribution.
Example: The table for the number of boys and girls for classes 6, 7, 8, 9, and 10 is shown below. Represent the data on a Double-bar graph.
Solution:
The double-bar graph for the table given the question,
Data Handling
Data Handling: Nowadays, managing and representing data systematically has become very important especially when the data provided is large and complex, This is when Data Handling comes into the picture.
Data handling involves the proper management of research data throughout and beyond the lifespan of a research project. This process includes establishing and implementing policies and procedures for securely storing, archiving, or disposing of data. It encompasses both electronic and non-electronic means of data management to ensure the data’s safety and security at all stages.
Statistics is another term for data handling, and it is useful not only in the fields of Math and Science but also in the fields where the representation of data is required. Let’s learn about some forms of Data handling, including the graphical representation of data and how they work.
