28.05.2021, adminUsing histograms, stem and leaf diagrams and box plots to compare distributions. Back-to-back stem and leaf diagrams may be required. Drawing of histograms, stem and leaf diagrams or equations for edexcel maths user plots will not be the direct focus of examination equations for edexcel maths user. Calculation of mean, mode and median, range and interquartile range will not be the direct focus of examination questions.
Students will be expected to draw simple inferences and give interpretations to measures of location and dispersion. Significance tests will not be expected. Data may be discrete, continuous, grouped or ungrouped.
Understanding Equations For Edexcel Maths 5 Years and use of coding. Students may be asked to illustrate the location of outliers on a box plot. Any rule to identify outliers will equations for edexcel maths user specified in the question.
