#### STATISTICS**:H**

**1. Infer properties of populations or distributions from a sample, whilst knowing the limitations of sampling**

**2. 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,
- tables and line graphs for time series data and know their appropriate use

**3. Construct and interpret diagrams for grouped discrete data and continuous data, i.e. histograms with equal and unequal class intervals and cumulative frequency graphs, and know their appropriate use.**

**4. Interpret, analyse and compare the distributions of data sets from univariate empirical distributions through:**

- appropriate graphical representation involving discrete, continuous and grouped data,
**including box plots** - appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers,
**quartiles and inter-quartile range)**

**5. Apply statistics to describe a population**

**6. Scatter graphs**

- use and interpret scatter graphs for two variables
- recognise correlation (positive, negative, no) and 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
