Histograms and Frequency Density

The video tutorial explains how to calculate the number of babies with birth weights between 2.5kg and 4kg using a histogram. It involves understanding the histogram bars, calculating the areas of bars representing different weight ranges, and determining the number of babies by converting area measurements into numerical values. The tutorial also discusses the methodology and marks allocation for solving the problem.

How many squares represent one baby on the histogram?
