This week math was so easy and I learned the lesson a day later then everyone else because I had a doctor’s appointment. The lesson our class learned that day was about mean, median, mode, and range. Here is an example.
You get a set of numbers: 1,5,3,4,4,6,9
Then you put them in order: 1,3,4,4,5,6,9
After that, you start by doing the mean part of the problem. That is where you add all of the numbers together and then divide them by how many numbers were in the problem. In this case, there are seven numbers in the problem so we divide 1+3+4+4+5+6+9=33 by seven.
The median is where you take them middle number and that’s your answer so the answer for this problem would be four. If there are an even amount of numbers, you add the two numbers in the middle and then divide them by two to get you answer.
The mode is where you take the number that is mentioned twice and that is your answer. If there are no number in the problem that are on twice, then you would just put no mode for the answer.
Finally, you would do the range which is very easy. All you need to do here is subtract the smallest number in the problem from the biggest one.
For me, all of this was easy and you have to remember, I came to class late so it should’ve been harder. I hope you learned enough to try this out by yourself!
