Understand & Calculate the Median of Data in Statistics - [6-8-7]

View more at www.MathAndScience.com. In this lesson, you will learn what the median of a data set is, why the median is important, and how it differs from the mean and the mode of a data set. Also, we will practice calculating the median and interpreting the result. In order to find the median, we arrange the numbers from least to greatest, the look for the numerical value that lies in the center of the data set. The center value is then the median. If we have an even number of data points, then we won't have a single center value. In that case, look for the two values that lie in the center and average them to find the median. We prefer to use the median when outliers are present in the data set.

Can you please make a part 2 of the “introduction to chemistry” video? Explaining atomic structures and bonding, stoichiometry, metals, the periodic table, electrolysis, and organic chemistry.. if these are too many topics for 1 video then please make more parts if you can, but covering all theses main topics of chemistry would help me a lot. Your way of teaching is so unique and simple so it would be really nice if you would make a part 2 of the chemistry video you made 5 years ago

You're the best teacher in the world 👏👏👏

I love how he teaches Math

[@JohnnySins0]

Math and science always finds a way to make people's day happier, he has inspired me to start my own channel😊👨‍🔬

The way you teach is really great! I hope i have a teacher like you :)

Can you explain for me when do we use the median, mode, mean, or range whenever the question asks us to find the average?

[@RebbecaMubiana]

I'm enjoying maths now thanks alot❤❤

[@dido1803]

Hi there, I enjoy watching your program. This particular subject really touched my curiosity. What is the percentage of the number would you consider to be outlier?

[@amirmilito8558]

Thanks uncle my name Amir from somaliland you greatest teacher of the world

[@jfjkdkjfj]

TEDIOUS!!!! Could have done that in less than 10 min.

[@ingrfhfa2423]

Brilliant sir

[@celsocahilog8733]

Real genius

[@hemarajue2736]

It make sense to remove outliers from the data sets. For instance, in a group of 5 trees having heights 2,3,4,5, and 100 feets, their mean doesn't represent reasonable height.

Good lesson thanks!

Hello My dear teacher

[@SoFarSoBook]

Everyone always calculating the mean, but nobody ever calculates the kind.

[@arlenejames6070]

What happens if you have six data points, what would the median be?

[@aiistyt]

The initial example has mean = median, is this advisable

[@haeleth7218]

The median and mode are the best averages. The mean is a terrible average.
