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.

Variability, a key concept in statistics, refers to how much data points differ from each other. Statistical questions require collecting data with variability to answer. For example, asking about the average number of cars in a parking lot on Monday mornings is a statistical question. video https://cdn.kastatic.org/googleusercontent/3J1gLnSfXhNOtKLBGm1Kk2nHDaRCTmjPOpCSPz5Otv_F_r9Bum5YyyJTaEHsWHUHqlaxFr7Z79n0Ps1cPHOS6Es Statistical questions Statistics is about collecting, presenting, and analyzing data.

For example, there will likely be variability in the data collected to answer the question, "How much do the animals at Fancy Farm weigh?" but not to answer, "What color hat is Sara wearing?".

We'll start by asking a statistical question—one that can be answered by collecting data that can vary. Then, create a plan to gather and analyze numerical data to answer the question. article
