Maths Performance Task: Statistical Journal (Individual)

Statistics cover mostly the bar graphs, pie chart, histogram, line graph etc. Mostly it just covers the way to learn and express information on graphs and charts.
I learned how to draw mostly all the graphs and to learn the properties of each graph and chart.
Statistics is used for gathering sales too, companies use graphs to record their income and their progress.
From my personal experience, i have used graphs to calculate the amount I spent on certain activities so i can plan day and not lose track of what I do.I also use them to record the amount of the electricity bill, so I know if the electricity bill is going up or down to know when to buck up and start conserving... Statistics can also be used in subjects in school such as science as we use them to calculate increase in the amount of things.
Writers writing the news also use statistics to show the information and the data to let readers better understand their reasons and explanations, eg. in a the news suddenly population of people start decreasing in a country the writers than gather the information needed and make a graph for eg. line graph to represent the decrease in population...These information are usually quite truthful but sometimes statistics will lie some people don't do anything related to the subject thus giving an un-accurate answer.
LEARNING EXPERIENCES:
I have done a lot in my part in the project, I did the final table to conclude the information for each neighbourhood and buses, then I did modeling and creating of the charts and graphs, ( we chose to you pie charts only) So i did the conclusion and creating of the graphs and charts. While others did the other parts such as the organising of the positions for the graphs, and text. the texts includes Introduction
A brief description of the current situation/ problem/ issue purpose of this investigation
Objective
The objective or purpose of this investigation. What do you intend to find out from this investigation?
There are 4 suggestions were given in "Scaffolds #1 (3) Preparation for Statistical Analysis". That will help to inform hte reader the scope of your investigation.
Methodology
A brief description of the data collection process [see Scaffolds #1 (2) Data Collection]
Findings
A presentation of the findings.
You will organise the data in appropriate form of table and charts.
Pick appropriate charts so that the information/ data could be presented in a meaningful manner.
Statistical Analysis
From the table(s) and chart(s), what can you tell about the punctuality of the bus services?
You are likely to use terms like frequency, central tendencies like mean, median & mode and percentages to describe what you observe (from the table/ charts).
Inferences
What conclusions did you reach on the basis of evidence and reasoning
Conclusions
Judgement or decision reached by reasoning
Recommendations
Strengths of our group, we have not much strengths in our group the one and most important one in our group was that we have the teamwork, we were able to plan and split the work out to each members with problem so that we could finish the task on date, and time.
DIfficulties:
We had some difficulties though eg.One of us did not know what was going on, he did not understand how to do the task assigned therefore we had to take quite a lot of time explaning and doing part of it for him, but overall we fared quite well.
IF I was to be able to this task again I would try to plan the whole process out accurately so we can manage the time well and meet the deadline without any fuss or hurry.
In this task I also learnt a lot from my friends to meet new friends and know my classmates more often, I hope to do more of such task.
