The Data Analysis course offers a deep dive into two key approaches to analysing and modelling data – analysis class modelling and data normalisation.
The course has recently been updated to include a module on data analytics, the interrogating and interpreting of data for the purpose of business decision making. The data analytics component looks at how data can be analysed with a business focus, offering critical insights which can drive decision making and pinpoint why some projects succeed and others fail. Techniques used to validate data against stated requirements are also explored.
Presented to you by one of the expert training consultants pictured below. Each member of our Data Analysis training team brings substantial data analysis, data modelling and data analytics experience to the programme.
