POSSIBLE LESSON PLAN FOR STATISTICAL INVESTIGATIONS LEVEL 4

Key ideas
Resources needed
Achievement objectives
Previous to starting unit: Taking the survey

Register your class to do the survey. Allow a day for this to be confirmed.

Students to do the CensusAtSchool online questionnaire.
CensusAtSchool home
This requires about 50 mins to collect measures and then about 15-20 mins to answer the questionnaire online.

Prepare the resources in the making measures document. This resource includes a lesson plan.

Collect student data cards in at the end of the lesson. These can be copied and used as a resource in the class in the introductory lesson.

Students go online to complete the survey. They will need a registration code.
  • Deciding on what the variable is for the survey question.
  • Deciding how to measure the particular variable.
  • Gathering the data by making the measures or finding the information needed.

Making measures document
online at
Needs station cards prepared.

Tape measures
Rulers
Data cards to write on
  • determining appropriate variables and data collection methods
  • gathering multivariate category and measurement data
Posing investigative questions

Lesson plan (draft)
posingquestionslevel4.doc

What makes a good summary investigative question?
  • check that the variable that is being investigated is clear eg heights, fitness level etc
  • check that the investigative question is general in format and allows for analysis to be made of the whole group not just an individual eg what are typical heights...
  • check that the group that is being investigated is clear eg year 9 students in 9BA, this group of year 8 students
  • check that the investigative question is able to be answered with the data you have eg there is enough data and the variable being investigated is in the data set
  • is the investigative question worth investigating, that is, will the information obtained be useful to someone eg kiwi bird typical weights may be of use to DOC staff or other conservation groups

Making displays using data cards

Lesson plan (draft)
usingdatacardslevel4.doc
  • posing investigative questions
  • initial look at making displays using data cards
  • initial description of displays
  • formalising what makes a good investigative question for summary situations



Data cards
either copies of class data cards or made up sets from CensusAtSchool.

Excel spreadsheet of data cards, blank data cards for students to fill in, variable cards.
year9posing.xls

Entire data set as a fathom file.
year 9 posing.ftm
This has individual collections for the sets of four pages, so students can work with their group as data cards and then electronically using Fathom (or tinkerplots).
  • conduct investigations using the statistical enquiry cycle
  • sorting, and displaying multivariate category, and measurement data to detect patterns and variations
Analysis tools

  • sorting, and displaying multivariate category, and measurement data to detect patterns, and variations
  • communicating findings, using appropriate displays.

Pulling it all together

Using music as a theme.
lesson plan (draft)
Music top 40 data
download information from:
music top 40

Suggest get album and/or singles sales from current month (4 weeks worth) and previous two-three years for same month.
Depending on capability you can get a pdf printout which has album, singles, compilations, radio air play and other information. Reasonably rich data set.

Can also download the top 50 singles and albums back to 2000.
  • conduct investigations using the statistical enquiry cycle
  • sorting, and displaying multivariate category, and measurement data to detect patterns and variations
  • communicating findings, using appropriate displays.
Informal comparisons

MUSIC
Compare top 50 album sales across the years, top 50 singles sales across the years, compare top 50 album sales with top 50 singles sales by year.

CENSUS AT SCHOOL
Compare boys and girls using the data cards. Combine two groups of cards and separate the girls and boys.
Download the top 50 singles and albums back to 2000.
download information from:
music top 40
  • comparing distributions visually
  • communicating findings, using appropriate displays.
Time series

MUSIC
Take a particular song or album and track its position on the music charts.
REACTION TIMES
Using sleeping sheep or similar reaction time application track reaction time over 20-40 repeats.

  • gathering, sorting, and displaying time-series data to detect patterns and trends
