how to determine what is a Graphical Comparison and what is a Numerical Comparison?
Graphical Analysis:
The analyses of data done through graph techniques to determine the optimal output is called Graphical analysis. One of the powerful tools used for data evaluation are the graphs. The graphs help in making summaries of characteristics of data in effective and efficient manner. Using graphical techniques, the complex equations or tests of statistics and mathematics can be interpreted.
For instance, the graphical techniques used to interpret the data on the environment are histograms, box plots, and probability plots. Basically, the graphs provide the information about the shape of distributions, the relation among the different variables and data sets, outliers, and trends. Since the graphical techniques are qualitative in nature, so the accurate conclusions cannot be made based on these techniques only. These techniques are used with quantitative statistical evaluations.
Some graphical techniques are described as follows:
1. Time Series Methods
- Box-plots 3. Scatter plots 4. Histograms
