Accepted Answer

Hi everybody and welcome. Let's move on to our next problem. A university conducted a survey asking students how often do you eat breakfast. The responses and their frequencies were never 30, occasionally 45, sometimes 60, often 80, always 110. Construct a frequency bar graph. And we're given the template for the graph. I already has the title, frequency of Breakfast consumption among students, a little key showing a light blue bar, meaning frequency, or Y axis is labeled frequency. And has 11 lines or 10 lines and then the top and bottom, and our X-axis is labeled responses. So note that we're asked about frequency, not relative frequency. So we're going to use the values themselves as our Y values. So, first, let's look at our uh Y range to decide how we're going to divide our graph, what are these lines going to be labeled. So, our Y range goes, well, from 0 through 110 as our highest value. And counting these lines, we said we have 10 lines and then 11 at the top of the graph. So, it's pretty straightforward to make each of our lines represent 10 answers. So, each line equals 10, with 11 lines that will put 110 right at the top of our graph. So, we'll label our frequencies here, 0 at the bottom, 10. 2030, 40, 50, 60, 70, 80, 90, 100, 1010. Even divisions and we can fit all of our answers. So, now let's start filling in our frequencies. So, we start with never on the X axis. Our frequencies are already in order of how often, never through always. So, we can start with never. So it's kind of logical order there. Again, these aren't um, officially it's it's not a numbered system, not ordinal, but it makes logical sense to have them in order of how often they're eating breakfast. But these are just responses, so they don't need to be in a particular order. So, never was 30. So, we put a line that will be the top of our bar at 30, and then two vertical lines going down to create our bar. We're then going to fill it in in light blue, since to go with that key, but uh I'm going to go through and draw all the bars first. So then, on the X axis, right, we write occasionally, I'll be our next response. Occasionally it was 45. So, we draw a line in between the lines for 40 and 50. I've got that there. And then 2 vertical lines going down to make the bar. Next one is sometimes. And that was 60 responses. So put a line on 60. Or horizontal line at the bar for 60. Two lines down, the next one is often. Which had 80 responses. So, draw a horizontal line, a line for 80. And then finally always. Which had 110 responses, so that is just going from top to bottom of our graph. Excuse my very wobbly lines there, straighten them out a bit. So, there we go. We can see we have a bar for each of our answers, the frequencies of breakfast consumption, we use the actual um answer frequencies there. So now we'll just fill these in. To make these bars light blue to match our key that's given where light blue bar. Signifies frequency. So just fill all those bars in in light blue. And there we have it. We have constructed a frequency bar graph for the question, how often do you eat breakfast? Our Y axis being the frequency, our X-axis being the different responses, and our bars light blue bars representing the frequency of those particular responses. See you in the next video.
