# S3-1: Conduct investigations using the statistical enquiry cycle: gathering, sorting, and displaying multivariate category and whole-number data and simple time-series data to answer questions; identifying patterns and trends in context, within and between data sets; communicating findings, using data displays.

The statistical enquiry cycle has five phases that relate to each other. Some enquiries follow these phases in sequence but often new considerations mean that a statistician must go back to previous phases and rethink. The phases are:

At Level Three students should be able to pose questions that they want to investigate, consider the appropriate data they need to collect, gather and sort the data in order to develop an answer to their question. The data involved should be multivariate so it should include many variables, for example gender, age, height, eye colour, bedtime, etc., so that relationships between the variables can be explored. Students should be able to ask summary questions (of a variable), for example what is the usual range in height for 10-year-old students?, comparison questions, for example are girls taller than boys?, and relationship questions, for example do older students go to bed later than younger students? Data displays, including tables and graphs, expected at Level Three are tally charts, frequency tables, pictographs, bar graphs, strip graphs, and pie charts for category data, dot plots and stem and leaf graphs for whole-number data, and simple line graphs for time series data. Students should be able to use computer technology to create these displays to find patterns, including trends over time, in data as well as to communicate their findings to others. They should be able to justify their choice of display/s with reference to the patterns they wish to highlight.

## Data Squares Level 3

- Units of Work
- Statistics
- Level Three

This unit provides a way of looking at multivariate data from a group of individuals. Data squares hold several pieces of information about individuals, and by sorting and organising a set of data squares, things can be found out about the group.

## Giant Mystery

- Units of Work
- Statistics
- Level Three

The unit explores relationships between the hand length, width, span of a person and their height and other body measurements. By using the hand print of a giant, students are able to use relationship between hand size and body size the find out how big the giant is.

## Hanging out for Hāngi

- Units of Work
- Statistics
- Level Three

In this unit students are faced with the challenge of ordering the right amounts of food to put down in a hāngi for the whole school. They carry out a statistical investigation into the preferred choices of food of the school population.

## Sports

- Units of Work
- Statistics
- Level Three

In this unit data about sporting activities is collected and presented using stem-and-leaf graphs and bar charts.

## Fridge Pickers

- Units of Work
- Statistics
- Level Three

In this unit, using our fridge as the context, we collect data and present these as dot plots, strip graphs and pie charts.

## Paper Planes

- Units of Work
- Geometry and Measurement
- Level Three

In this unit, students investigate one variable to see if they can make a paper plane fly further. They use scatter plots to establish a possible relationship between variables, then use what they have found to make a paper plane to enter into a class competition.

## Carrots

- Units of Work
- Statistics
- Level Three

In this unit we investigate the amount of water contained in a carrot and we plot the "weight" of the carrot using a line-graph as the water in the carrot evaporates. The students also pose their own carrot questions for investigation.

## Planning a Statistics Investigation L3
