Lesson 3: Histograms

Creating a histogram

A histogram is a graphical display of data using bars of different heights. In a histogram, each bar groups numbers into ranges. Taller bars show that more data falls in that range. A histogram displays the shape and spread of continuous sample data.

• In my mind, histograms and bar graphs are very similar. What situations would histograms work better than bar graphs? I feel like you could just organize the categories into buckets and then just use a bar graph. Why choose the histogram?
• well histograms would be grouping numbers and bar graphs would be grouping categorical things like cats or dogs not the age of cats or dogs.
• So please tell me the difference between a bar chart and a histogram because I thought that histograms had frequency density as the y-axis with interval on the x-axis.
• On a bar chart, the bars are not connected. On a histogram, they are connected!
• So, if I did a histogram, I could record ages of people in my school and in the primary?
P.s- upvote for the question if you think it's a good way to teach kids. I might do it
• Is a histogram the same as a histograph?
*is a histograph actually a thing?*
• um,yes they are they may be written differently but still they the same thing.Im not fully sure but search it up!
• Do the bucket intervals need to have the same value? For example, do they all need to go by the same number, or can they have different ranges?
• You can set the bucket size however you like, but you'll get much better clarity with equal sized buckets. Remember that the purpose of making a histogram (or scatter plot or dot plot) is to tell a story, using the data to illustrate your point. Using equal-sized buckets will make your histogram easy to read, and make it more useful.
• Who is still alive?
• Me >
• is it a histogram or histograph?
• histogram!
• How do you find the interval?
• Find the interval? I don't get it. If you meant the domain, it's from the lowest number to the highest number.
