Data Analysis is a process of collecting and examining data in order to gain meaningful insights and inform data-driven decisions. Data Analysts utilize a range of techniques to discover useful patterns, trends, or relationships demonstrated by large amounts of data. The specific methods used by Data Analysts depend on the type of data they are dealing with, but they often use software such as Tableau and Microsoft Excel to summarize, arrange and analyze raw data sets. A Data Analyst can help a client make more informed decisions and insights by providing them with in-depth data analysis that can be used to inform their decisions and strategies.

The task involves analysing about 50 sheets of prediction results from ML models. The task is to analyse the data sets independently or together with the training data sets and then determine which model will give the best prediction results based on the prediction history available in the 50 data sets. The analysis should be done only on the data with or without training data sets and not the ML model. The analysis is concerning the results of the 50 data sets available. After the analysis, I will be able to tell which model is best suited for the 51st data set.
