Exploring Histograms and Box Plots

This video lesson covers key statistical concepts such as mean, mode, median, and range. It explains how to calculate these values and interpret them in data sets. The lesson also explores various types of graphs, including bar graphs, frequency graphs, histograms, dot plots, and box plots, and discusses how to interpret data from these visual representations. Additionally, the video addresses the concept of skewness in data distribution and how it affects the mean and median.
