Hello students, in this blog we are going to discuss about the tools of data analysis but before discussing the tools of data analysis statistics. We should be familiar with the data analysis term. Data analysis is the process of summarizing the information by using the following steps,
-Inspecting the data.
-Cleaning the data.
-Transforming the data.
-And last modeling the data.
There are various tools that analyze the data more clearly and more precisely. Some of them are: -
1. Histogram: - This is the most common technique for data analyzing. This is the graphic technique that shows the frequency distribution.
2. Survey: - Usually the surveys are organized by the various NGOs to collect the data. This is done publicly so that we can know the behavior, opinions and knowledge of the public.
3. Scatter diagram: - In this type of data analysis tool we create the diagram for the numerical data.
4. Series of experiments: - In this type data analysis tool, we predefine the some series of experiments on the particular data or information. Then data passes through the various series of experiments and meaningful data is drawn.
5. Box and whisker Plot: - Various types of data sets are plotted on the single graph.
6. Check sheet: - It is like ms excel sheet that stores the data in tabular format, so that data can easily be understand by everyone. It is a prepared form for data collecting and data analyzing.
7. Control chart: - It is used to control the data process. It compares the data that change from one state to another. (know more about cbse board papers, here)
But mostly used data analysis tool is histogram.
This bog will be helpful for Grade IX students to understand the Tools of data analysis.
In the next session we will discuss about Data representation methods.
