OCR Maths: Higher GCSE - Check In Test 12.03 Analysing data

A 10 question test on Analysing data, comprising: 5 questions on procedural calculations; 3 questions on reasoning and communicating mathematically; and 2 problem solving questions. At the end of the test there is an extension activity which will allow more able students to stretch themselves. This resource is ideal for either formative or summative assessment and can be used in lesson time as a topic assessment, starter or plenary activity or for homework or revision.
Topics include:
Calculate the mean, mode, median and range for ungrouped data.
Find the modal class, and calculate estimates of the range, mean and median for grouped data, and understand why they are estimates.
Describe a population using statistics.
Make simple comparisons.
Compare data sets using ‘like for like’ summary values.
Understand the advantages and disadvantages of summary values.
Calculate estimates of mean, median, mode, range, quartiles and interquartile range from graphical representation of grouped data.
Draw and interpret box plots.
Use the median and interquartile range to compare distributions.
Recognise graphical misrepresentation through incorrect scales, labels, etc.
Plot and interpret scatter diagrams for bivariate data.
Recognise correlation.
Interpret correlation within the context of the variables, and appreciate the distinction between correlation and causation.
Draw a line of best fit by eye, and use it to make predictions.
Interpolate and extrapolate from data, and be aware of the limitations of these techniques.
Identify an outlier in simple cases.
Appreciate there may be errors in data from values (outliers) that do not ‘fit’.
Recognise outliers on a scatter graph.
