HANDLING DATA

Design and use data collection sheets for grouped and continuous data
Collect data using observation, controlled experiment, data logging, questionnaires and surveys
Gather data from secondary sources
Design and use two way tables for discrete and grouped data

Draw and produce pie charts for categorical data, and diagrams for continuous data including line graphs for time series; scatter diagrams; frequency tables and stem-and-leaf diagrams

Calculate mean, range and median of small sets of data with discrete then continuous data;
Identify the modal class for grouped data.

Draw lines of best fit by eye, understanding what they represent

Understand and use the probability scale
Understand and use estimates or measures of probability from theoretical models

List all outcomes for single events, and for 2 successive events, in a systematic way
Identify different mutually exclusive outcomes and know that the sum of the probabilities of these is 1.

Interpret a wide range of graphs and diagrams and draw conclusions
Compare distributions and make inferences, using shapes of distributions and measures of average

Have a basic understanding of correlation as a measure of the strength of the association between 2 variables
Identify Correlation or no correlation using lines of best fit

Compare experimental and theoretical data
Understand that if you repeat an experiment they will get different outcomes, and that increasing sample size leads to better estimates of probability

Interpret social statistics including index numbers; time series; and survey data.
