Analyzing Histogram Observations

The video tutorial explains how to compare the total number of observations between two histograms, A and B. It involves counting the observations in each histogram, summing them up, and then calculating the difference. Histogram A has a total of 42 observations, while Histogram B has 36, resulting in Histogram A having five more observations than Histogram B.
