Flashcards for CCEA GCSE Statistics (2260), split into the specification's own content areas: planning and data collection, problems with data, types of data, processing and representing data, reasoning and interpreting results, probability, the normal distribution and the binomial distribution, and statistics in real life. Higher-tier cards say so.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

  • Does a correlation between two variables prove that one causes the other?
    No, correlation does not necessarily imply causation
  • If a new value equal to the current mean is added to a data set, what happens to the mean?
    It stays the same
  • Universal set (in a Venn diagram)
    All the objects of interest in the context being studied
  • What kind of data can a pictogram represent?
    Categorical data, or grouped discrete data
  • Standardised score (z-score)
    The number of standard deviations a value lies above or below the mean
  • How can an uneven or inconsistent scale on an axis mislead a reader?
    It can make values look evenly spaced, or directly comparable, when they are not
  • Frequency tree
    A diagram that shows the frequencies of a series of outcomes as branches
  • A running total of frequencies up to and including each class
    Cumulative frequency
  • Petersen capture-recapture method
    A method of estimating the size of a population by marking a sample, then checking how many marked individuals appear in a second sample
  • Experiment (as a data collection method)
    Collecting data by carrying out a test under controlled conditions
