The Histogram refers to a graphical representation that shows data by way of bars to display the frequency of numerical data whereas the Bar graph is a graphical representation of data that uses bars to compare different categories of data. Clearly, the bracket with the highest population is the 20-40 age bracket. Each bar typically covers a range of numeric values called a bin or class; a bar's height indicates the frequency of data points with a value within the corresponding bin. 81) Which of the following statements about histograms are true?
