**Scheme of work: GCSE Higher: Year 9: Term 1: Statistical Measures**

- Interpret and present discrete and continuous data using appropriate graphical methods, including bar charts and time graphs.
- Solve comparison, sum and difference problems using information presented in bar charts, pictograms, tables and other graphs.

- 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
- Construct and interpret stem and leaf diagrams
- Apply statistics to describe a population

- A frequency table is used when the sample size increases beyond simple calculations being possible from a list.
- The median average of a class width is used as the mid-pint when calculating the mean from grouped data.

- Students often find it difficult to calculate the median average from data presented in a frequency table.
- When sorting continuous data into a grouped data table students often struggle to fully understand the inequality notation.
