---|
interpret and construct tables, charts and diagrams, including frequency tables, bar charts, pie charts and pictograms for categorical data, vertical line charts for ungrouped discrete numerical data, and know their appropriate use | including tables and line graphs for time series data | |
Notes : including choosing suitable statistical diagrams.
S3

---|
| | construct and interpret diagrams for grouped discrete data and continuous data, ie histograms with equal and unequal class intervals and cumulative frequency graphs, and know their appropriate use |
S4
Basic foundation content | Additional foundation content | Higher content only |
---|
interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: | | |
- appropriate graphical representation involving discrete, continuous and grouped data
| | |
- appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers)
| | - including quartiles and inter-quartile range
|
Notes : students should know and understand the terms: primary data, secondary data, discrete data and continuous data.

S6
Basic foundation content | Additional foundation content | Higher content only |
---|
use and interpret scatter graphs of bivariate data | | |
recognise correlation | know that it does not indicate causation draw estimated lines of best fit make predictions interpolate and extrapolate apparent trends whilst knowing the dangers of so doing | |
Notes : students should know and understand the terms: positive correlation, negative correlation, no correlation, weak correlation and strong correlation.
