Maths teacher here: this is NOT a histogram- notice how the y axis is frequency and not frequency density. To find the frequency of each bar on a real histogram, you would multiply the class width by the frequency density

this actually helped me so much and thank you for not sounding boring like corbettmaths

it is not a histogram. it is the frequency diagram. the histogram should have frequency density in y-axle.

I tied this method to visualize and appreciate the median concept:
Instead of a graphical histogram, make a linear set of observations:
{6, 6, 6.5, 6.5, ...9 times.. ...7.5, 7.5, .... 25th & 26th value... 7.5, 7.5, .. 8.5, 8.5, 9, 9}

Clearly, the 25th & 26th values are 7.5. Median value: 7.5

0:23 It's the interval between 7.5 & 8 😀
Can we get more specific - with regard to what that median is, though? How would we figure that out?
Thanks!

shouldnt it be frequency density on the y axis for this to be a histogram?

What about when u have an odd number of bars?

What is the meaning of median sleep amount???

You shouldn't have pulled random numbers that don't relate to the graph. This makes it confusing to what you're looking at since both sides of the frequency and sleep hours are similar. When someone like me is comparing what I have to what you might have, in this simplistic view, I cannot figure out what you're doing step by step.

How would I know to look at the frequencies? 🤔

But this isn't a histogram, though.. histograms have freq. density on the Y axis, not frequency, and the class widths aren't all the same - this is just a bar graph..?
