first of all I would to begin with the things that I have learned from this project, well actually I become much better using R language I knew how to build plots with it and the libraries that were required to that as well. also that was a good practice on solving hypothesis testing problems and it's better when you build the question by yourself and type the code to solve it.I also learned about how to import data from excel to R studio to use it for analyzing your dataset and I started with two different examples of hypothesis testing using two different confidence level after I wrote the code and fixed it's errors we got the values for these two analysis.
however, after I finished them I started to understand the concept of Regression analysis & Correlation Analysis they are a little bit similar to each other but the challenge here was to make sure that the results of this data will reject the hypothesis null or not.
therefore, for the last analysis that we chooses in this project which is Chi Square test of independence at the begging it was a little bit confusing but after a few research on google , YouTube ,slides and also previous recording lectures finally it was pretty clear to me and them I wrote the code to which includes building the contingency table and also printing out the critical value and so on.
finally, at the end of this reflection I would like to say that I really enjoyed working in this group project we were all like a team working together to solve the problems and to understand the analysis, it was very beneficial to me and to my future career as well, I really become very interested in data analysis after this great project and I hope I will use this knowledge that I have gained from this project and the whole course in my career. thank you...
