What is the Large Data Set (LDS)?
The large data set (LDS) is a pre-released set or sets of data that will be used to teach you important statistical concepts throughout the course.
Why am I learning to work with the LDS?
The purpose of the large data set is that learners experience working with real data in the classroom and explore this data using appropriate technology, such as Microsoft Excel.
Will I have access to the LDS in the exam?
No. According to OCR, "Learners will NOT have a printout of the large data set available to them in the examination but selected data or summary statistics from the data set may be provided within the examination paper... Knowledge of the actual data within the data set will not be required in the examination, nor will there be a requirement to enter large amounts of data into a calculator during the assessment."
...Then how can I be examined on the LDS?
In the exams, it will be assumed that you are aware of the contexts of the large data set and that you have used a spreadsheet when working with the data in the classroom. They might include questions/tasks which:

In the exams, it will be assumed that you are aware of the contexts of the large data set and that you have used a spreadsheet when working with the data in the classroom. They might include questions/tasks which:
- assume familiarity with the terminology and contexts of the data, and do not explain them in a way which provides learners who have not studied the prescribed data set the same opportunities to access marks as learners who have studied them
- use summary statistics or selected data from, or statistical diagrams based on, the prescribed large data set
- are based on samples related to the contexts in the prescribed large data set, where learners’ work with the prescribed large data sets will help them understand the background context
- require learners to interpret data in ways which would be too demanding in an unfamiliar context
