Work through the list without notes. If you cannot do a statement, follow its link, then come back. Guide = study guide; Practice = practice questions.
Understanding
- I can explain what iterative and interactive use of a program with data means. (Guide: “Why use a program at all?”; Practice Q5)
- I can state the difference between transforming, filtering, combining and visualising. (Guide: “Four processes on data”; Practice Q1, Q3, Q4)
- I can explain how combining data sources, clustering and classifying help gain insight. (Guide: “Four processes on data”; Practice Q6, question 10)
- I can explain why results depend on the quality and size of the group of data. (Guide: Worked example 2 interpretation; Practice question 9)
Skills
- I can trace a loop that filters a list and give its output. (Guide: Worked example 1; Practice Q2, Q8)
- I can trace a loop that transforms every element or keeps a running total. (Guide: “Tracing list-processing code”; Practice Q3, Q7)
- I can modify a condition to change what a filter keeps. (Guide: Worked example 1; Practice Q8)
Reasoning
- I can plan a sequence of processing steps for a question and say what each shows. (Guide: Worked example 2; Practice question 9)
- I can explain why a first result may lead to a second question. (Guide: Worked example 2 passes 2 and 3; Practice question 9)
- I can say what to check before trusting a result from a program. (Guide: “Common misconceptions”; Practice questions 9 and 10)
