Lesson 3: Data Presentation and Visualisation

Introduction to Data Science

In this lesson you will meet some more techniques for pre-processing and cleaning data. These include how to change the data type of a value, such as from text to number, and how group similar items in the data set.

In this activity you will create charts that focus on one numerical feature to continue your exploration of differences in the weather around the UK, using the EdExcel large data set.

In this activity will create diagrams that visualise relationships between life expectancy and other features, using the MEI large data set about countries.
