In a bar graph if you don't display all the data, is the problem still incorrect?

From what I know, yes. The answer is incorrect if you don't have all the data on the graph

can you do half numbers?

Another reason to do halves is if there's a certain pattern. For example, if there's a bar chart that counts by even numbers 2-10 and the question tells you to plot 3 and 7, you can just put 3 between 2 and 4 and 7 between 6 and 8.

When something is quantitative it means that it can be represented as a quantity, which is to say a number. In the case of statistics a variable is quantitative when it deals with numbers. For example, a teacher's favorite class is chemistry, their favorite class is a categorical variable. But if you say the number of teachers whose favorite class is chemistry is 3, that would be a quantitative variable, because it deals with numbers.

which side is the x- axis and which is the y- axis?

The *x-axis* is the horizontal (side-to-side) line that goes from left to right. In this bar graph, the x-axis is labeled with courses: physics, chemistry, geometry, history, and language. The *y-axis* if the vertical (up-and-down) line that goes from bottom to top. The y-axis is labeled with numbers to show the number of teachers. Hope this helps!

what if the question said 10 teachers physics what would you do?

If you want to make a bar graph to show 10 teachers. You could say 2 teacher. So, You could draw 5 because 2*5 = 10

Can you use decimals in plot diagrams? Would the be wrong?

Yes you can use decimals. On a plot diagram each line has a number. You would put 1 2 3 4. For decimals, on one line put 1, the 2nd line leave blank, the 3rd line would be 2. You would see 1 / 2 The / is the line with no number in-between 1 and 2 and that would be 1.5 Add more lines dependent on decimals. So 2.3 would be 1 / / / / / / / / / 2 / / / / / / / / / / The 3rd / after 2 is 2.3 each / is .1 / this is a line as the numbers, except you leave it blank. Even if it starts at 2.3 you do not put 2.3 under the line.

How do you use the bar graph on the actual question?

If you are asking how to create it, you click on the top of the bar and drag up or down.

A bar graph is a graph to make it easier to read. no one wants to read 5 mice ate five cheases. so insted, they make a bar graph

Video transcript

20 teachers were asked about their favorite course. 7 teachers said language. 3 teachers said history. 9 teachers said geometry. 1 teacher said chemistry. 0 teachers said physics. Create a bar chart showing everyone's favorite courses. So we've got the bar chart right over here. And let's see what we need to plot. So it said, 0 teachers said physics, which is surprising to me since physics is arguably my favorite course. But let's plot what the data has. So physics-- so right now it looks like it's halfway between 0 and 1, so you actually have to bring the physics down to 0. Let's see, chemistry. Let's see, 1 teacher said chemistry, so we got to bring chemistry up to 1. Now, 9 teachers said geometry. So geometry, let's bring that up to nine. 1 teacher said chemistry. Oh, I already read that. History. History. 3 teachers said history, so let's bring history up to 3. And then language. 7 teachers said language, so let's move this up to 7. And I think if I didn't make any careless mistakes, we should be done. Yep. Very good.
