Structure, Checklist & Useful Information
θ Title: “Where are houses most expensive?”
Hypothesis and Strategy
θ Define each of the terms “where”, “houses” and “expensive”. θ State your hypothesis (NOT a question!).
θ What is the variable (the data)?
θ *What diagrams will you use?(Pick at least two higher level ones. The graphs must be ideal for helping you decide if your hypothesis is true or false.) θ †What statistics will you calculate? (Pick at least two higher level ones. The statistics must be ideal for summarising the data.) θ Check your statistical language is accurate and clear.
Selection and Collection of Data
θ Name the source of your data (the website).
θ Why have you used this data?
θ What is the population?
θ Name the type of sampling you will use.
θ Justify your method of sampling.
θ What is your sample size? Why is it large enough?
θ Describe your method of sampling clearly and in enough detail so that someone else could replicate your sample. θ Check your statistical language is accurate and clear.
Use of Graphs and Diagrams to Test Hypothesis(Two sets of tick boxes for two different types of graphs). θθ Write down any tables/calculations you need to use for drawing your graphs (e.g. frequency table with frequency densities, pie chart radius and angles, outliers for box plot). θθ Draw your graphs accurately.
θθ Label your graphs.
θθ Interpret your graphs – what do they tell you about the data? You’re aiming for sophisticated inferences!
Use of Calculations to Test Hypothesis(Three sets of tick boxes for at least two different types of statistics). θθθ Show your method of calculating clearly (e.g. in a table/using ∑ notation/…) θθθ Check your calculations are correct!
θθθ Write down your results to a sensible level of accuracy. θθθ Interpret your statistics – what do they tell you about the data? You’re aiming for sophisticated inferences!
