Storyboard Text
- Now lets move on to the median.The median is when there is a set of numbers and
- Does any one of you know whats the mean?
- Today we are going to learn about mean and median.Lets start with the mean.
- Its okay because that means were learning something new
- No I dont!!!
- Mean is the average of a set of numbers.
- Then you divide by how many number there are. There are 4 so 4÷ 24=6 so the mean is 6
- For example4,6,8, and 6First we add them all which equals to 23
- Now lets move on to the median.The median is The middle number of a set of numbers.
- Then you cross the numbers from left to right one by oneuntil you reach to a number so for the example the median is 4
- For example,1,6,4,7,8,3,4Now you order them from least to greatest1,3,4,4,6,7,8
- If you have an even amount of numbers here is what you do.4,5,4,2,7,9Then you order2,4,4,5,7,9
- Then you cross out one by one from left to right until you reach two numbers.So the numbers are 4 and 5 are the middle numbersNow you find the mean for 4 and 5 Which is 4.5.
