Statistics

Level 2

I can ...

• collect, sort and display data  and discuss outcomes

• predict the likelihood of events

• say the possible outcomes for events

• make a block graph using materials

• make a pictograph

• talk about graphs and give simple explanations

• ask questions about data

• talk about the differences and similarities in data

Early Level 3

 I can...

• predict the likelihood of events using words and numbers

• pose investigative questions

• estimate probable outcomes

• collect and display data in a variety of ways

• give feedback to others about their investigations

• make summary statements by reading the data

• make connections between the data, the summaries and the real world

• find the chances of an event occurring by carrying out a trial

Level 3

 I can...

• create a question for investigation - summary, compare, relationships

• plan an investigation and gather multi variate data

• plan a process for collecting, analysing and displaying data

• carry out the investigation and record data in tally charts, frequency tables and graphs

• make judgements about the trends in my data

• interpret my results sharing my findings with an audience

• analyse different graphs, raw data and generate new questions 

• find the chances of a simple practical event by completing a trial

• use the evidence from the statistical investigation to make a judgement that relates to me and/or the real world

Level 4

 I can ...

• create a question for investigation based on an issue or interest

• plan an investigation and gather multi variate data, ordering it using appropriate charts, consider sample space and bias

• graph the data in the most effective way using pie graphs, bar graphs, histograms, strip graphs, stem and leaf, box and whisker graphs

• interpret the information displayed in a variety of different graphs

• make judgements about the trends in my data and discuss trends, clusters & outliers 

• interpret my results sharing my findings with an audience and respond to their questions

• sort and present data digitally using tables, spreadsheets and charts

• write a report about the implications of the data

• find all of the outcomes of simple chance events using tables, lists & probability trees, compare the likelihood of events using trials 

Level 5

 I can...

• Pose investigative questions about a wider population.

• Plan and conduct surveys & experiments using the PPDAC cycle

• Consider sample size, random sampling, avoidance of bias, systems of collection and process of data

• Recognise whether data needs to be cleaned, discuss reasons for variation in data

• Collect samples of multivariate data, identify patterns within, between and beyond the data noticing unusual values

• Communicate findings with appropriate displays and generalise findings in context

• Use technology to sample, collate, sort and display data

• Understand & explain why statistical investigations might be presented in particular ways.

• Make connections between experimental chance results & theoretical models

• Understand that the accuracy of experimental models increases with greater sample size

• Calculate probability using fractions, percentages & ratios
