7.8 Histograms
Here you’ll learn how to create a frequency distribution chart and how to construct and interpret a histogram.
Suppose you’re working in a card store and you notice that the cards have different prices. You pull 15 cards out of

5.65. If you divide this data up into 0.50 intervals how can you construct a graph of your findings?
