When taking exams, you may come across questions that require you to analyze large data sets. To ace these questions, it is crucial to familiarize yourself with the data beforehand. Exam questions typically provide partial data sets for calculation purposes.
Each exam board has its own specific data set, covering a wide range of topics. For example, the Edexcel exam board focuses on weather data from various locations in the UK and other countries. This allows for the examination of different variables, such as:
Pro Tip: 1 knot is equal to 1.15 mph.
Pro Tip: Oktas has an 8-point scale with 0 Oktas representing a clear sky, and ⅛ Oktas meaning one-eighth of the sky is covered by clouds.
It is possible for the data set to have missing values, which may be indicated as "n/a" or "not available".
Let's take a look at an extract from a large data set and explore the type of questions you may face.
