Video transcript The owner of a restaurant wants to find out more about where his patrons are coming from. And we’d want to show where the actual median is. Then we have a He wants to create a graph that helps him understand the spread of the distances– this is a key word– the spread of distances and the median distance that people traveled or that people travel. And then the whiskers of the box and whisker plot essentially show us the range of our data.

Box and Whiskers Plot (solutions, examples, videos)
Rotate to landscape screen format on a mobile phone or small so,ving to use the Mathway widget, wisker free math problem solver that answers your questions with step-by-step explanations. We want to think about the box part of the box and whisker essentially represents the middle half of our data. Well, we have 1, 2, 3, 4, 5, 6, 7, 8 data points. Basically a box and whiskers plot looks like this: We have this 7 right over here.

We lrsson keep going– 30, maybe Sometimes people leave it in. And we’ll also see the median of the two halves of the data as well.
Constructing a box plot
So both of those 1’s are right over there. Formula for percentage Finding the average Basic math formulas Algebra word problems Types of angles Area of irregular shapes Math problem solver Math skills assessment Compatible numbers Surface area of a cube.
Now it should be relatively straightforward to find the middle of our data, the median. And then the middle of the top half, once again, we have 8 data points. Draw three vertical lines at the lower quartile 12median 22 and the plts quartile 36just above the number line.

Let me do that same pink color. So let me draw a number line, so my best attempt at a number line. I am at least 16 years of age. And they go as low as 1. Everything you need to prepare for an important exam!
Arrange the data in ascending order. So our middle two numbers are going to be shisker 11 and this So there you have it. So I have the 1’s, 2’s, 3’s, 4’s, no 5’s. So here are all the distances traveled. So that separates the third quartile from the fourth quartile. Join the lines for the lower quartile and the upper quartile to form a box. So how many data points do we have?
Do we have any peoblem
So let’s start off by attempting to order our data. Real Life Math Skills Learn about investing money, budgeting your money, paying taxes, mortgage loans, and even the math involved in playing baseball. There’s one 8 right over here.
So I got that 1 right over there. Basic math review game – The one and only math adventure game online. So the two middle numbers are this 2 and this 3, three numbers less than these boxx, three numbers greater than it.
So what a graph captures both of that information?
