MAD (mean absolute deviation) helps you get a sense of how "spread out" a data set is. Learn how to compute MAD in this video. Practice this lesson yourself on KhanAcademy.org right now: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/cc-6-mad/e/calculating-the-mean-absolute-deviation--mad-?utm_source=YT&utm_medium=Desc&utm_campaign=6thgrade Watch the next lesson: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/cc-6-mad/v/mean-absolute-deviation-example?utm_source=YT&utm_medium=Desc&utm_campaign=6thgrade Missed the previous lesson? https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/cc-6th/v/calculating-interquartile-range-iqr?utm_source=YT&utm_medium=Desc&utm_campaign=6thgrade Grade 6th on Khan Academy: By the 6th grade, you're becoming a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.) About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

If you had zero in the set, do you still have to subtract it from the mean?

I get it, but I don't see how it's useful. What sort of problem can I solve by knowing the Mean Absolute Deviation of a dataset?

How to solve for the Mean Absolute Divination? Well, first find the mean of the data set. Then calculate how far the # is from the mean. Add them up, and divide by how many # there are. The Mean Absolute Divination could be a whole # or a decimal. Hope this helps. Give a like if you understand, and a comment if you don’t.

rahim bukhari (10 months ago)
Hey Sal great video. Here's a question. When does MAD become redundant and we switch to Standard Deviation? In other words what are the limitations of MAD? Could u plz explain with an example? I'd appreciate it if u have already made a video on it. If u have could u plz send me a link? Thanks. Keep up the great work... 👍

XxKalicoKatxX (2 years ago)
If the graphs are too complicated and you want to solve the MAD quicker, just do this: find the mean of the data sets, then find out how far each number is from the mean (ex: 6 is 3 away from 3) and then add all of those distances together, then divide by how many data points there are.
