![]() ![]() I'm Rachel and thank you for learning with me today. That does, this doesn't always happen, sometimes the mean can be different than the median and often is, but in this case, we found the mean from the box and whiskers plot and it ends it up being five. Sample problem: Make a box and whiskers chart in Excel for the following data set: 25, 145, 145, 148, 178, 178, 198, 201, 222, 210, 565, 589, 485, 333, 358, 158, 257. ![]() So, five in this case is our mean as well as our median. Now, we're going to divide by the number of numbers we have one, two, three, four, five. So, in this case, we're going to add one plus three, plus five, plus seven, plus nine one plus three is four plus five is nine, plus seven is 16, plus nine is 25. How to Determine the Mean When Only Given the Box & Whisker Plots - YouTube 2024 Google LLC Box and Whisker plot is a visual representation of a group of numbers. What does that mean? That means that we add all the numbers together and then we divide by the number of numbers. Display the lower and upper quartiles and the median salary on a box plot. So, the mean is going to be the average of those numbers. calculate these quartiles for the list of salaries. Box and Whisker plot is a visual representation of a group of numbers. Five is the median of those numbers and we want to find the mean. How to Determine the Mean When Only Given the Box & Whisker Plots. So, if the data is one, three, five, seven and nine, then those are the numbers that we're using. Draw a line across the middle of the box at the median value. ![]() Draw a box with ends at the hinge values. Scale it appropriately for the range of data. The box and whisker plot calculator can be used to find the IQR. The (IQR) is the difference between the lower and the upper quartile. For this graph, the left whisker end is at approximately 0.75. Lower outer fence lower inner fence - (1.5 x H-spread) 7. The first step in constructing a box and whisker plot is to find the median, the lower quartile (Q1) then the upper quartile (Q2) of a given set of data.Then you need to find the interquartile range or the (IQR). Well, in a box and whisker plot, we have it written on a number line, so we actually have all the numbers should be written on this number line that are in the data. The minimum is the far left hand side of the graph, at the tip of the left whisker. Hi, I'm Rachel, and today we're going to be going over how to determine the mean when only given a box and whisker plot. ![]()
