Sec 1 Maths Perf Task Reflection

Statistics is being used from case to case in daily life. Statistics always come from Mass amounts of Data, and can be represented in many forms. Statistics displayed in different forms, may show hidden patterns and trends which may be of use to the reader/analyser that aren't shown when in raw data form. Statistics basically summarise the table of contents and data, so everything can be digested at one glance by the reader.

Statistics can help us greatly, and benefit different people of different walks of life.For example, Sports recruiters check out potential athletes.They track their progress,compare them with other athletes and choose the best of the best. All this could only be available because of the presence of Statistics,which help show comparison easily with just a glance.However,these data maybe represented differently for different purposes.

Before we go on to the different ways a set of data can be represented, let's circle around what a specific set of data to be should consist of,or even what can it be made of.

Data is anything that involves information. There are two types of data, "hard" data and "soft" data. Hard data are data that have fixed values,and would be universal. Soft data is the opposite of Hard data, as it may vary from one person to another who collects the data, as it may be affected by bias. The accuracy of the Data may also be affected by the person collecting it, and of course other circumstances and factors like:

>Human Errors in Transferring/Digitizing of Data

>Wrong Classification of Numbers

>Person collecting Data is Unorganized and mix up Data collected

>The Method used to collect the Data

Data can be represented into different forms, for example:

>Line Graphs (Mostly used to show Progress of a company/being, also used to show hidden Trends and Patterns)

>Bar Graphs (Used to show Comparison between data sets)

>Histograms (Usually makes use of Continuous Data and bars arranged in Continuous order)

>Frequency Table (Can hold smaller sets of data but keeping it exact.)

>Stem & Leaf (Can hold large sets of data while keeping its original numbers and Require a Key/Legend like 1|10)

>Dot Diagrams (Horizontal Axis's Labels are Continuous and Require a Key/Legend)

Personal Reflection:

We have came up with a new method of representing the data into a easy to compare Bar Graph. So that even if people who read out statistical Poster feel that our Conclusions has some mistakes, they can see from the Bar Graphes itself and come up with their own conclusion. Although most likely it would be the same one as ours. The group volunteers to take on different roles, and would finish the work asked to complete by the dateline the group gives. This saves us a lot of time, as some work cannot be started without the others being completed. All the members in my group have this sense of urgency, as we in fact have really little time to do this Maths Performance Task. I helped Sandy with coming up with Bar Charts in our format and fill in the Table in Google Spreadsheet. If there is a similar Project in the Future, I would like to collect the Data together with my group as the Data is not completely accurate.
