The video tutorial by Sean Ian explains the concept of the interquartile range (IQR) in statistics. It covers how to find the first and third quartiles of a data set and calculate the IQR by subtracting the first quartile from the third quartile. An example using data from a hot dog eating contest is provided to illustrate the process. The video concludes with a summary and encourages viewers to ask questions or request further videos.
