My responsibility in the analysis of data:
I in charge making some chart and script the data we collected and link it with our aims.
Actually all our member we have the same responsibility but I am more on the technical analysis.
The biggest challenge you see in this project
The biggest challenges in this project is not the programming skill that need to make the graphical representation but is to determine the relationship that we need to link between the question that we might want to form so that we can make the question and by collecting the data from responses to have the best result for our aims of the project. For this situation, team working plays an important roles . We get along well and we did not shy to provide ideas when we do the brainstorming for question about the survey and we all accept the all people perception and take into consideration and make the decision after the discussion and argument.
Mistake we made :
To be honest , I think that we have done quick some mistake. In this project we did not plan properly. Everything is fine but it is not the best that we can do . I think that we can done better. We should plan the relationship between our question or the data we might collect properly first before we create the questionnaire and distributed it. I will do better in the next analysis project is have any.
I also need to admit that we do not really use the most proper graphical re presentation to show our data to others.
The lesson that I learned and the skill that I learned :
With this PSDA project 1 , I get exposure in R programming when we want analyst the data , esxplore our data and create a graphical representation such as pie chart , bar plot, frequency distribution , histogram ,scatter plot and dot plot. There are many resources in internet. We just need to surf the internet and browse out the commands or codes we need. There might have website that will provide codes that we cant use as Rstudio we used are the newest and the person who write the website or share the information might make mistake too. There also might have codes that are very high level and I cannot understand , but I found out that if we out some time in it and do not give up we still can understand it and apply it in the PSDA project 1. I learn a lot of R programming keyword or we said specified code such as fitter() that aids in filter out the data we need , stem(). There are a lot of wonderful codes that helps make our graphical presentation more presentable , more meaningful .
I learn not only the technical analysis but also the way we analyse the data before we do the technical analysis. We have to set our priority or our goal first and always remember on that. Then we create or think about the relationship of the data we collected from the question we asked in the questionnaire with our priority or our goals of our survey. For this , I learned from the mistake we did .
In this project , I learn how to make more presentable graphical representation using the codes available in the internet such as “ggplot()”for making better bar plot,histogram “filter()” for filtering out the data , “pie3D()” for making 3D pie chart, and etc. I also get to know some library needed such as “ggpubr” for “ggbarplot()” to make better barplot that can represent more than two data , expss for making better frequency distribution, “dplyr” for “ filter() ” and “ggplot2” for ggplot that can make better barplot and histogram , “plotrix” for 3D pie chart .
After the project , I had improve my soft skill which is communication and team work . I able to communicate and deliver my idea well and we had quite a good sharing opinion on each others’ points.
Feeling after conducting the survey:
I felt grateful after the survey as a lot of people willing to help us by answering the questionnaire that we posted. This also provide me an opportunities to do analytic job. I also found out that it is quite fun when we doing r programming , it have the same sense and feeling when doing other programming when we see our outcome. It feel amazing.
Reminder for myself :
“<-” and “=” is the same but
“<-” can use anywhere
“=” is needed when calling functions to avoid assigning globally.Only allowed at the top level ( expression type in command prompt) or as sub expression in a braced list of expressions )
