Part 1: In my own words, statistics is the collecting of a large group of data from many sources and classifying them into different ways, like bar graphs, pie charts, line graphs,or the stem-and-leaf diagram, and then interpreting the data presented by us in the classified ways. From what i have learnt from chapter 16, statistics are used to normally benefit the researcher or the community around him or her, and the information collected can be easily collected into bar graphs, pictograms, pie charts,line graphs, and stem-and-leaf diagram. A graph will always have a title and a key to tell the reader what the data drawn means. Statistics collection must be planned ahead of time to avoid unnecessary obstruction. In our real life, statistics are used for economical purposes for our Singapore government, information for the government to know about the population number of citizens of a country so as to plan for the upcoming future, like the number of houses they have to build for the citizens of the particular country, or for science experiments where line graphs, bar graphs and pie charts are commonly used for collecting the data or frequency of something happening, or the amount of things present at one point of time. From my personal experience as a student, my encounter with statistics has been countless. From the newspaper i read sometimes, i read the graphs which represent the amount votes for a particular subject which they asked from residents and citizens in Singapore. In our geography we sometimes use graphs to know the population of the citizens and how it affects the country’s land uses. For maths especially, the e-learning lesson was the greatest encounter with statistics as we had to collect the data of the frequency which the buses arrive on time, early, or late, and put the data into graphs and tables and put them on the class maths blog. Statistics are very useful for us in the future if we are going to pursue economics and the stock markets as a job. Newspaper articles like i said before use graphs, mostly bar graphs, pie charts and line graphs to show us the extent of a particular topic, example, the latest Singapore election. But sometimes statistics lie as usually for pie charts they put in an approximated percentage of the real number of votes or of something.
Part 2:
My group has worked together with cooperation with each other and everyone had done our part. While one of us was drawing the main part to put our data and interpretation, the rest of us were working on the frequency graph and the way to present our data in other graphs, and grouping the right and accurate data up to not arouse confusions. My group’s strengths are being cooperative, responsible for our own work, and talking things out sensibly without arguing much. My roles were to get the group together for meetings, being a leader and leading them, and gathering data, with some planning of the base outcome of the poster. The difficulties i faced while doing this was while gathering 20 bus numbers, some of it were unusable as the collector might have made a typing error and we had to change the number of the buses and spread the buses out for each neighborhood, and we could not assume if the frequency and timing of the buses. If we could do this again in the future, i hope to do more detailed planning for the data collection and the way we are going to do the classifying of the data in more details.
