Check them out below. 1) View Solution A histograms is a form of bar chart; however, there are two main differences. In order to make this work, when drawing a histogram, we plot frequency density on the y-axis rather than frequency. Therefore, once we know what an area of 25 small squares represents, we can add this to 30 (the number of bags represented by the 30 – 40 pound category). Since this is half of the total of the 30 – 40 pound category, the number of bags between 30 and 40 pounds is: In the 40 – 55 pound category, the area is 1.5 times the 30 – 40 pound strip, so this represents: So far we have accounted for the first 75 bags of flour (50+75=125) so haven’t reached the 93^{\text{rd}} bag of flour yet. In order to draw a histogram, we need to know the frequency density for each row of data. By subtracting the 75 bags that weigh less than 55 pounds from 93, we can work out that the 93^{\text{rd}} bag will be the 18^{\text{th}} of the 35 bags between 55 and 65 pounds. GCSE_HistogramQuestions. We have made the assumption that the number of bags that weigh between 80 and 95 pounds is \frac{3}{5} of the number of bags of flour that weigh between 70 and 95 pounds. The frequency density for each group is found using the formula: \text{frequency density} = \dfrac{\text{frequency}}{\text{class width}}.
