A line graph.
Which graph is used to display categorical data?

When do you use a linegraph?
A line graph is used to display data points over a continuous range, typically to show trends over time. It is particularly effective for illustrating changes in quantities, such as sales, temperature, or population, as they evolve. Line graphs can easily highlight patterns, fluctuations, and correlations between variables, making them a valuable tool for analysis and presentation.
Difference between data flow diagrams and hierarchical charts?
Data flow diagrams (DFDs) visually represent the flow of data within a system, highlighting how data moves between processes, data stores, and external entities. In contrast, hierarchical charts, such as organizational charts or structure charts, depict the relationships and structure within a system or organization, focusing on the hierarchy and arrangement of components. While DFDs emphasize data interactions and processes, hierarchical charts focus on the organization and levels of authority or components. Thus, they serve different purposes in system analysis and design.
Does there is any tool for normalization?
Yes, there are several tools for data normalization, including libraries and software like Python's scikit-learn, R's caret package, and data processing platforms like Apache Spark. These tools often provide built-in functions to scale and transform data, ensuring it fits within a specific range or distribution. Normalization is commonly used in machine learning and data analysis to improve model performance and accuracy.

What are the four steps of data manipulation?
The four steps of data manipulation typically include data collection, data cleaning, data transformation, and data analysis. Data collection involves gathering raw data from various sources. Data cleaning ensures the data is accurate and consistent by correcting errors and removing duplicates. Data transformation modifies the data into a suitable format for analysis, and finally, data analysis involves interpreting the manipulated data to derive insights or inform decisions.
What are the key features to consider when choosing survey scanning software for data collection and analysis?
When choosing survey scanning software for data collection and analysis, key features to consider include compatibility with different types of surveys, ease of use, accuracy in data capture, ability to handle large volumes of data, robust reporting and analysis tools, and data security measures.
What are statistics in math?
"Statistics is the study of the collection, organization, analysis, and interpretation of data." (Wikipedia)
What science process is used when you tell the characteristics of an object.?
