Statistics Topics We Solve

Data Presentation & Interpretation

Mean, median, mode, range, interquartile range, variance, and standard deviation calculated from raw data, frequency tables, and grouped frequency tables. The solver also interprets histograms, cumulative frequency diagrams, box plots, and scatter graphs.

Probability

Single event probability, combined events using AND and OR rules, conditional probability, tree diagrams, Venn diagrams, and two-way tables. Each probability is expressed as a fraction as preferred by UK mark schemes.

Probability Distributions

Binomial distribution, normal distribution (standardisation using z-scores, finding probabilities, inverse normal problems), and at Further Maths level, the Poisson distribution and continuous random variables.

Hypothesis Testing

Hypothesis tests for proportion (binomial), correlation (PMCC), and mean (normal distribution). The complete testing procedure: stating hypotheses, calculating test statistics, finding critical values, and writing a conclusion in context.
