How can you use bar graphs to compare quantities in real life situations

You can illustrate it by comparing two quantites in a correlational basis. Like the price times the time of how a courier delivers a package or a internet speed vs the data cap and land area and the investment.

Bar graph display directly the variables which are the rate and ratio of the numbers to visualize and display the results, these contrasting the different outcomes. On the contrary, histogram is used in grouped frequency parameters. Moreover, as little as the given five parameters or data set this will be ineffective and will result to a bar graph only and basically, the suited option is the aforementioned vertical graph to display the numbers. To expound on the definition of histogram it is used when the frequency is grouped. For example the data set of 1-5, 6-10, 11-15 and 16-20 this now can be used and applied to illustrate histogram because of the number and quantity of the given data.

We can use bar graphs to solve many real life problems. A bar graph is simply a graphical display of data using bars of different heights. To answer this question let's take an example. Suppose you are a student and want to know which kind of food people prefer in your urban area. So, you did a survey to find the answer. In this way, you found that:

40 People prefer Hamburgers50 People prefer Hot Dogs60 People prefer Fried Chicken10 People prefer Roast Beef

So, we can show the relative sizes using a bar graph. This is indicated in the Figure below. Therefore, you can see that most people prefer Hamburgers and few people prefer Roast Beef

Ithink the answer is d.
