We all had to do a class survey with a cunclusion this is mines.

My Conclusion is that most people like outdoor subjects and technology. This is my census at school.

Mean= The mean is basically the average number you plus all the numbers together then divide it by the number of numbers that there is. For example 30+30+30=90 you then divide it by three because there are 3 numbers so the answer is 30. Median= The median is the number that lies in the middle of a set of numbers. For example 1,2,3,4,5,6,7,8,9,10,11. the median is 6 because it is in the middle of all the numbers Mode= The mode is the most frequent appearing number. For example here are a set of scores 20, 60, 50, 60,35, 12, 60. 60 is the mode is 60 because it’s the most common number. Data Displays= Data displays are things like tally chart and stem and leaf graphs. Random Sample= Random sampling is a sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has a known, but possibly non-equal, chance of being included in the sample.

Bar graphs= A bar chart is a chart that shows scores through the height of the bar, the higher the bar the higher the points. The rectangular bars are usually spaced apart and go up ways not side ways.

Pie Graphs= A pie graph measures amounts by how big each chunk of the pie is. The bigger the chunk the bigger the score.

Histograms= Histograms are a way of summarizing data. For example the number of dry days in a month. A histogram looks like a bar chart except the rectangular bars are spaced apart

Stem & Leaf Graphs= A stem and leaf plot is a way of summarizing a set of data measured on an interval scale. For example measuring the thickness of someone's skinfold.

Key Questions

What is Census At School?

Census at school is a nationwide online survey for Year 5 - 13 students which provides real, relevant data and classroom activities.

The New Zealand Census gives data on Population and houses not how you bike to School or How heavy your bag is.

Have a look at the results from our 2006 answers to the questions in the Census at School 2009 questionnaire.

Collate the data to use it for comparison with at least one other year group within New Zealand and one International group of the same year group. Make sure you only use a couple of pieces of information not all of them and use 2006/7 data from sources. What conclusion can you come to?

Now choose one question to compare across Canada, Australia, South Africa, United Kingdom and New Zealand. What conclusion do you come to?
