Lesson+7+by+Luke

this lesson we talked about comparing data ......

Mr. Rad said we have already talked about the mode as something we can discuss when analysing data.

Then we talked about the meddian and what it is.

the median is the middle number of all the data in order from shortest our tallest etc ...

to find it we count up the number of data pieces and divide that into two. there are then two methods for finding the methods for finding the median.

if we have an odd number. eg. ( 3, 7, (9), 15, 21) 9 is the median.

then we discussed what if it is even ? eg. ( 6, 9, 11) (17, 20, 25) then we have to do more calcutaltions, that is we need to find the point that is halfway between 11 and 17. to find it we add 11 and 17 together = 28 then divide 28 by 2 which leaves us with 14 as the median.
