On what i know about statistics, it is about data collection o
f any kind and analysis of the collected data in large quantities. It is often represented in a graph with one line being the change in the amount variable and the other is change in time or group. Different graphs have different change in time or group such as a line graph is only used in the change in time while a bar graph can be both the change in group and time.
Statistics can be used to measure the quantity of almost any variable, ranging from the amount of water used, to the population of a city and to the change in the economy. One of my encounter with statistics is when i used to take the height of a growing plant during a science project. During then, i used the line graph as it can easily show the viewers the change in the height of the plant over the next few days.
In newspaper articles, statistics are usually used to show the economic movement, casualties from a natural disaster etc. such as the recent Japan earthquake and tsunami.
This image shows the intensity of the quake in different parts of Japan. It contains a legend which shows us the intensity of the certain place marked by different colors. In my opinion, it is a good way to easily show a person immediately which part of Japan has the worst of the quake compared to bar graphs, although it shows which place has the highest intensity easily with the bar of highest intensity being the tallest and the name of the place. Not all statistics result may be correct or real, as it depends on the person making the graph, on wether he or she is biased or has wrong information about the statistic graph variable, such as the person may lie about his or her country's economic report, in order to show that his or her country's economic is better than what it should be. In my point of view, a statistic table should be taken by different reporters and then decide upon the most accurate and fair result.
ii) Learning experience.
I believe that my team has so far done a great job on the performance task, as we are able to come out with conclusions and graphs to represent our findings. My role in the project was to gather individual charts of different areas and compile them in the findings of the percentage of buses that came on time against the percentage of buses that did not come on time. After that, me and my group members discussed about the conclusion and how to present our data in the poster. I believe that my group members' strength lies in the ability to create a decorative poster and graphs as two of them are from media club. The main challenge was deciding on what hypothesis and conclusion we should have as our group takings were based on bus stops inside GRCs and a SMC. Also, we have to void some takings which were incomprehensible due to the fact that the reading could not be true, for example, if the person stayed only at the bus stop for one hour and thirty minutes, there could not be an occurrence of 12 buses that have an expected arrival time of 12 minutes. If i were to do a similar project such that some statistics have to be taken, i would prefer to take them on my own than to rely on other's taking, such that i know my own readings are reliable and consistent according to myself.
The three highlights for me during the past two weeks were the camp, the tower building challenge and meeting our new teachers. My lowest moments were when i first discovered that me and my friends from primary school were going to different classes, going into the class without knowing anyone at first and not doing the rock climbing obstacle during the camp. The greatest lessons during the past two weeks were learning about how to work as a team during the camp, tower building challenge and learning about SA, Situational Awareness. I learnt about myself that I am daring during the high elements and can make friends easily during the past two weeks. I am looking towards more group activities and more stuff to learn for 2011.
Communication is important as it is used for people to understand what you are trying to tell them example instructions, orders, requests or what you are feeling. My favourite form of conversation is verbal conversation as it is the easiest to express and the easiest for other people to understand. I would choose the form of communication by what form of conversation the other party is using. Difficulties that i mostly face in conversations is that when using verbal conversations, some people speak too fast or too soft, so i am not always able to understand them.
