Emma’s band wants to post a music video on YouTube, but they aren’t sure which of their songs should be featured. Emma’s best friend helps them choose by using Facebook contacts to conduct a survey, exploring the concepts of qualitative and quantitative data along the way. Viewers learn how to sample, present, and analyze data, generate histograms, frequency tables, stem and leaf plots, determine the interquartile range, and more. The video also defines random and non-random samples, dot and box plots, outliers, and other essential terms.
