Hi there. It might not be that your histogram is *wrong*, just that it is drawn to a different scale. If the question hasn't specified how they want the groupings broken up, then you can do it how you like. But in this case, there is only 1 data point between 1-1.4, and then none from 1.5-1.9, and then none from 2-2.4 etc. so it would be logical to choose bigger groupings. Lump more of them into each category, so to speak. The graph might be a little more meaningful that way. Hope that helps! :)

Hello! I got a little question about frequency table and frequency histogram. I have trouble with how should we group the data. For example: 4.3, 4.5, 4.7, 4.9, 5.1, 5.3, 5.5, 5.6, 5.2, 3.6, 2.5, 4.3, 2.5, 3.7, 4.5, 6.3, 1.3 I arranged like that: 1-1.4, 1.5-1.9, 2-2.4, 2.5-2.9.. etc. but when i checked the answer, it is wrong. They do it: 1-1.9, 2-2.9, etc and my histograms is wrong too. Could you please explain how to arrange it? thanks!
