Using nutritional data from a coffee shop as an example, the lesson highlights how variables can represent diverse aspects of a data set, such as drink type, calorie count, sugar content, and caffeine amount. video https://cdn.kastatic.org/googleusercontent/VoX1L5bEmGHX80BSI4lPLdERhFNGOhWwWM6N31m_DmMCQs0hxYYvHAS9XNbq2Rx2UWjx0_Ngj4HMQgbWYlWzU6A Identifying individuals, variables and categorical variables in a data set The concept of variables in data sets comes to life through an exploration of categorical and quantitative variables.
