3.Investigating Studies
:pencil2: 6. Misleading Reports
:black_circle_for_record: Bias in reporting
Slides:
Discuss types of bias in reporting.
Misrepresentation of graphs or conclusions
Observer bias
Transfer of findings to larger group
Story selection or omission
Questions:
Identify different types of bias in reporting. Discuss why they arise, how to identify them.
:black_circle_for_record: Misrepresentation of data
Slides:
Discuss misrepresentation/misinterpretation of data in reports, whether graphical, tabular or other.
Questions:
Identify ways in which data is misrepresented.
:black_circle_for_record: Policies from reports
Slides:
Discuss issues to be considered in the implementation of policies that result from studies reported in the media or elsewhere. Are the studies trustworthy? Were they reported accurately? Does the policy reflect the findings?
Questions:
Long answer; given a situation, explain whether a policy based on a particular report is warranted.
:pencil2: 7. Statistics in the Government and Companies
:black_circle_for_record: Use of Statistics in Organisations
Slides:
Show how companies and governmental departments use statistics to inform action, eg. type, location and/or funding of services and facilities. Statistics lead to inferences and conclusions, which lead to decisions.
Questions:
MCQ etc. about why organisations use statistics.
:black_circle_for_record: Investigating use of statistics
Questions:
Give examples of organisations using statistics to make decisions. Determine/explain whether the statistics support their decision.
Slides:
Making sure the decision follows from the statistics. Has the right conclusion been drawn? Is a given conclusion actually significant? Does the decision follow from the conclusion?

:black_circle_for_record: Sampling Bias
:black_circle_for_record: Sampling Bias long-answer
:pencil2: 5. Analysing Sampling Methods in Reports
:black_circle_for_record: Sampling techniques used
Slides:
Discuss making sure sampling method is appropriate (can rely on knowledge of methods from earlier lessons).
Questions:
Provide examples (real-world if possible, otherwise invented). Is the sampling method used appropriate?
:black_circle_for_record: Wording of questions
Slides:
Discuss how wording can bias results.
Leading Questions
Double-barrelled questions
Value Judgement Questions
Jargon
Double-negative questions
Questions:
Provide examples of survey/poll questions (real-world if possible, otherwise invented). Will the wording bias the results?
:black_circle_for_record: Sample size
Slides:
Discuss effect of sample size on validity of results. Could use n=sqrt(N) as a rule of thumb.(Sample size has already been mentioned in the first lesson.)
Questions:
Provide examples (real-world if possible, otherwise invented). Is the sample size sufficient?

NSW Curriculum
:spiral_note_pad: Investigate reports of studies in digital media and elsewhere for information on their planning and implementation (ACMSP277)
Investigate and evaluate the appropriateness of sampling methods and sample size used in reports where statements about a population are based on a sample
determine whether a sample used enables inferences or conclusions to be drawn about the relevant population (Reasoning)
critically review surveys, polls and media reports
identify, describe and evaluate issues such as the misrepresentation of data, apparent bias in reporting, sampling techniques used, and the wording of questions used to collect data (Communicating, Problem Solving, Reasoning)
discuss issues to be considered in the implementation of policies that result from studies reported in the media or elsewhere (Communicating, Problem Solving)
investigate the use of statistics and associated probabilities in shaping decisions made by governments and companies, eg the setting of insurance premiums, the use of demographic data to determine where and when various facilities may be built
use Australian census data to identify issues for the local area or state and suggest implications for future planning in the local area or state (Problem Solving, Reasoning)
