    What is statistics?

    Statistics collects, organises and summarises data through measures of central tendency and dispersion.

    Why it matters

    It builds data literacy and is examined through mean, median, mode and standard deviation questions.

    Key concepts you will practise

    • Mean, median and mode for grouped and ungrouped data
    • Frequency distributions and cumulative frequency
    • Range, variance and standard deviation
    • Reading histograms and ogives

    Tips that save marks

    • For grouped data, use class midpoints as the representative value.
    • Standard deviation is the square root of variance — do not stop at variance.

    Frequently asked questions

    How do I find the median of grouped data?

    Locate the median class from cumulative frequency, then apply the median formula for grouped data.

    What does standard deviation tell you?

    How spread out the values are around the mean — larger means more scattered.
