Hello everyone! Watch this video on mean, median and mode, and learn the song, so you can impress me in our next class! Besides, if you learn the words, you'll remember how to differentiate between the three terms. When you've done that, test yourself with the simple game that follows.

The lyrics for the song:

Mean, median and mode

Mean, median and mode

How do you find the mean?

Add up the numbers in the data set

Divide the total by the number of items

The answer is the mean or average

Mean, median and mode

But how do you find the median?

Arrange the numbers in order

From the lowest to the highest values

The middle number is the median

For an odd number of items

The average of two middle numbers

Is the median for an even number of items

Mean, median and mode

Mean, median and mode

How do you find the mode?

Just find the number that repeats most often

And that number is the mode

If you find no number that repeats most often

Then there is no mode

Mean, median and mode

Mean, median and mode

Mean, median and mode

I'll explain the examples shown in the video:

Mean:

Data: 1, 8, 6, 4, 6

Add up all the numbers in the set: 1+8+6+4+6, which gives the answer 25. There are 5 numbers in the set. You calculate the mean (also known as average) by dividing 25 by 5, which gives the answer 5.

Median:

Using the same data, you arrange the numbers in ascending order: 1, 4, 6, 6, 8. Since there are 5 numbers (which is an odd number), the one in the middle is 6 (1 and 4 to the left of it, and 6 and 8 to the right). So, 6 is the median.

If, however, there are 4 numbers (which is an even number) 1, 4, 6, 6, you'll have to add the 2 middle numbers, which, in this case, is 4+6. Then, you divide the answer by 2: 4+6=10. 10 / 2= 5. So, 5 is the median here.

Mode:

The mode is basically the number which repeats most often. In our example, the number that repeats most often is 6 (repeats twice). If there aren't any numbers which repeat (e.g. 1, 8, 6, 4), then we say that there isn't any mode.

Let's test if you've understood the concept by playing this game. Have fun learning! Oh, and don't forget to submit a comment so I know you've been here!
