Sec1 Maths Performance Task Reflection

Statistics are very important in real-life .

Business men cannot do business without statistics . Statistics can be used is various ways , such as helping people understand consumer’s behavior , knowing what they like and don’t like through research and conducting surveys . Statistics help accountants get the exact value of the money . Without statistics , Accounting is impossible .

Statistics can be used to make predictions based on raw data , it also helps in drawing valid inference, along with a measure of their reliability about the population parameters from the sample data. For example if the statistics shows that the amount of people buying product A is decreasing , then the quantity of product A being produced will decrease as time passes . Statistics help accountants get the exact value of the money . Without statistics , Accounting is impossible .

Statistics also helps in education . For example if someone is planning for the activities and methods of learning a certain topic , they can conduct a survey and if the statistic shows that more students like plan A , the person will then use plan A . We , as students , can also use the statistics to do our work and find the mean , median and mode for a certain question that we are working on . The methods of science are most reliable but conclusions drawn from them are only anticipated, because they are based on incomplete evidence. Statistical helps in describing these measurements more precisely. When conducting experiments , statistical methods are used to analyze the experiment’s results .

Housewives can also gain from using statistics . For example they can look at their utility bills and see in which area can they cut down on so that they can save some money for the family . When cooking , they can look at statistical showing that shows which ingredient is healthier and they can thus use that to cook healthier meals .

Statistics are also important when we are researching on a topic . Taking this performance task as an example , without the statistics , we would not be able to come up with a conclusion whether the buses are arriving on time .

So, without statistics , life around the world would be disastrous !

Statistics taken from different places can benefit different people .

Statistics taken from the newspaper can benefit the people who do not have time to watch the television or the computer but are interested in the different topics . For example if someone wants to find out about the Japan Earthquake , they can read the news paper and find out how many casualties were involved in the Japan Earthquake .

Statistics taken from the computer can benefit people who work almost all the time in the office .

We spilt up the work within our group members such that the two of us who stays in the West will gather information on the bus services in the West zone and the other two who stays in the North will gather information on the bus services in the North zone . Since there are two people who are in charge of one zone , the 5 bus services will be split between the two of us . The strengths of our group is that we are very cooperative and we are very on-task . When one another meets any difficulties , the others will try their best to help that person . My roles are to gather information on 2 of the bus services in the West . I also had to organise the poster and contributed to how we should design the poster . Some challenges we faced are that we were quite short of time so we did not really know who would do which role and could not split the roles equally so some people ended up having more roles than the others . If I could do this task again , I would spent more organising our roles and planing our task before doing it .

The following fractions share a common denominator: 1/6, 2/6, 3/6, 4/6, 5/6, 6/6.
1/6 is a recurring decimal.
Janice concluded that all other fractions with denominator are also recurring decimals.
I do not agree as some fractions can be divided equally and the decimals will come to an end but some cannot be divided equally and have recurring decimals

CNY Hamper Reflections

•What are we doing? What have we done?
- We are wrapping a hamper for the elderly . We bought things that we thing is helpful and useful to them to add in the hamper.
•How do we think that we are affecting the recipients of the hamper? What will be different for them?
- I think that we can make them feel that people care for them and they are not alone in this society. They might be happier and be more optimistic when facing problems as people will be there to lend a helping hand .
•What could be our next step to care for this group of recipients?
- We could visit them and express our care and concern and we could also accompany them to go out to exercise .

One of the highlights was the climbing the elements during orientation camp and also the campfire during the orientation week . The last highlight is the Tower Building exercise during the first week of the orientation .
The first 'low' moments was the time when we had to sleep on the hard wooden floor , secondly , during the time when we had to do our reflections . Lastly , when we were leaving the camp .
I learnt about the 3Rs , the rules we have to abide to in class and most importantly what applied learning is.
I learnt that there is nothing I cannot do if i persevere until the end .
I am looking forward to more group activities and class outings .

Communication is important as we need to communicate to give instructions , work together and interact with others .
My favourite form of communications is talking face to face . I think that it is respectful and easy to do.
We can decide which form of communications to use by looking at what we have to say . For example if our message is very long and complicated , we might choose to call the other party but if our message is short and sweet , we might choose to sent a short message the other party.
Difficulties we face might be the other party not understanding our message or we might not be able to understand others . We might also use the wrong form of communication .

Day 1 Mac Attack 1 - Activity 4: End-of-Day Reflection

Today , we went through alot of activities like the cheers and dance . We were also told about the 3 Rs ( Roles , Rights , Responsibilities ) and we had to do class and group discussions about what we had learnt. I enjoyed some icebreaker games and got to briefly know each others . I learnt the meanings and definitions of the 3Rs . Some of my classmates also shared some of their thoughts about the 3 Rs .
I chose to come to SST as I am interested in Science . I hope to excel in Science and improve my other studies too. I aspire to become a doctor and to do that , I have to work even harder than I am doing right now.
I have gained more knowledge on the 3Rs after a day's lesson.
