Project Reflection

For project 2, it covers chapter Hypothesis testing until chapter ANOVA where I need to implement all of the topics that I learned in the project. This project requires me and my groupmates to do analysis testing which covers a few tests which are  1/2-sample testing, correlation test, regression test, we also need to choose whether to do ANOVA, chi-square test, or goodness of fit test.

In this project, I and my groupmates need to choose a dataset for our study. we need to study the dataset and decide which variables we need to choose for all of the tests we need to do.  In other words, we learn about teamwork where it was very important in order to complete the task.

Other than that, each test requires us to do some calculating and we need to use R programming for the calculating. Therefore, in this project, we learned how to use R programming for calculation. R programming is very widely used in statistical data analysis, so it was useful in calculating statistical data in this project and quite easy to understand.

Last but not least, for this project it was very important to distinguish the variables that we need to use, so for project 2, i learned how to identify variables that suitable to use for each test. For example in a correlation test, I need to identify the variables with ordinal, ratio, or interval data types. So in the dataset, I need to select the variables with these data types in order to complete the task. I also learn how to implement correlation in r programming because this project requires me to calculate the statistic data using r programming.
